Optimus-switch and acpi_call-dkms vs. linuxxx-acpi_call

I was about to upgrade my nvidia driver from 430 to 455, but I noticed a conflict between acpi_call-dkms and linuxxx-acpicall

[philippe@Probook-450 ~]$ LANG=C sudo pacman -S  acpi_call-dkms

:: acpi_call-dkms and linux54-acpi_call are in conflict (acpi_call). Remove linux54-acpi_call? [y/N] ^C

My aim is to be able to completely switch off the nvidia card.
I found no optimus-switch update and wondering how it will behave with newer nvidia driver if the optimus-switch code is not update ?
I have noticed my battery is not lasting as before, when optimus switch were completely switching it off.
Any advice ?

optimus-switch should ideally work regardless of the driver/kernel version. You don’t need acpi_call-dkms if you use a “standard” kernel since there are linuxZZ-acpi_call packages.

Thanks. Good to know. Hope I can manage to upgrade painlessly. But according to what’s going on on testing branch, I will wait a little longer to update nvidia driver:
