efibootmgr just orders/reorders the priority of the various grub bootloaders of all the distros on your machine. Once you decide which distro’s grub should be booted first over the other distros’ grub, how you customise that chosen grub is a different issue.
For me I make custom entries in /boot/grub/custom.cfg so I can decide on the order of menu entries.
For things like grub background, timeout, etc, you need to edit /etc/default/grub

my own custom grub is the last thing I want !! 
There should be no need to change order of GRUB entries
Manjaro GRUB does not function like other distributions that default to the first menuentry
If a user chooses another menuentry, GRUB will save the user choice and continue to boot from that menuentry
If you want to change boot options in GRUB see this previous discussion for how to modify /etc/default/grub configuration – Help setting default grub entry

We discussed this many times. Some folks want Windows as the default for family members etc.
So you can choose the option to fix the main entry, remember the last boot.
The easiest way to do this (GUI) is to hit Alt_Space to pull up krunner.
type kate /etc/default/grub
(or select and copy the text, hit Alt_Space then Ctrl_V)
There are instructions in the file…
So you can set the ‘SAVEDEFAULT=false’ to stop the grub remembering what you last booted.
Then you change the number on GRUB_DEFAULT
When you’re done you must run grub-update too.

No I am not looking for default entry, I am looking for ways to change the position of the different options in grub. Not necessary but I like all the oses one after another and then all the other entries
Like currently it is:
Manjaro
Adv opts for Manjaro
Windows
How can I make it look like:
Manjaro
Windows
Adv opts for Manjaro
grub-customizer would change files in folder /etc/grub.d/ to change the order of menuentry items
But changes made by grub-customizer could cause GRUB to fail when system is next updated
If you want to change the menuentry boot order by modifying the file order in /etc/grub.d/
I suggest you make a backup copy of the files and be aware of how to fix GRUB if changes do not work out
GRUB/Restore the GRUB Bootloader - Manjaro

You move entries (select and drag them to order them).
menuentry "Manjaro Linux" {
set root=(hd0,2)
linux /boot/vmlinuz (add other options here as required)
initrd /boot/initrd.img (if the other kernel uses/needs one)
}
So move the “Manjaro” menuentry to the top, then “Windows”

efibootmgr will change this boot order in the BIOS, not in GRUB.

I know it works but what it changes I do not know, if it changes the bios how does grub catch up?
That’s it, it doesn’t affect GRUB. It affects the boot order for EFI, the BIOS, and NOT GRUB.
For uefi systems, each distro’s bootloader (usually grub), if installed, gets installed in that ESP partition. So all it is, is a collection of each distro’s grubs.
Efibootmgr just helps you select which distro’s grub you want to control the booting of your whole machine. Once you have selected the controlling grub, you need to know how to tweak it, so get familiar with editing that distro’s /etc/default/grub file.
After update-grub the grub.cfg resets and I have to do the steps each time grub updates itself. Is there a permanent way?
Probably not as the file you modify is generated on each update. You could maybe craft a pacman hook specifically to modify this file, but that’s kinda risky if your hook doesn’t work properly.
I have saved my modified part as a backup on a 2nd ssd, when grub updates(doesn’t update frequently) I will just paste my saved portion of the grub.cfg to the new grub.cfg.

You shouldn’t edit grub.cfg.
You need to follow instructions a little more carefully - either that or just leave it alone because it’s working ok at the moment.
kate /etc/default/grub
and don’t forget to sudo update-grub.
What is the output of:
grep "^menuentry" /boot/grub/grub.cfg | cut -d "'" -f2
