No - it is your responsibility - you do it your way…
It is a simple yes-no question.
Upstream Arch split the linux-firmware into vendor specific packages - which required the user to manually intervene and install the system specific packages.
Manjaro took another approach - linux-firmware-meta is an umbrella for all firmware packages.
This was done to provide an easier transition for the individual user.
So answering yes will replace the old linux-firmware with all available firmware packages.
You you know what firmware packages are applicable for your system you can remove the umbralla
sudo pacman -R linux-firmware-meta
Then you can list firmware packages
$ pamac search linux-firmware- --no-aur | grep Installed

Remove those you know you don’t need
Manjaro Linux is for people taking the deliberate choice to use Linux.
If you don’t want to update your system - that is deliberate choice - a choice I don’t condone - but will respect.
Unlike Windows - you can actually choose to do just that…
Install - disable update nagging - and be done with it.
But with the choice not to update also comes the inability to sync new applications because such action requires an up-to-date system.
To help users which want it that way, I wrote this guide some time ago

Afterthought - you can use flatpak - although not by guarantee - they should run no matter the the underlying system.
