I’m using this kernel parameter for custom resolution on grub
GRUB_CMDLINE_LINUX=“rhgb quiet video=DP-3:1920x1080MR@164”
But after kernel update my custom resolution not applied. I need grub update after every kernel update.
Is there a good solution for this?

When a new kernel is installed grub id supposed to copy the kernel command line from the active kernel.
Check that the video= option is set on all your kernels using grubby --info=ALL
.
I do not edit the GRUB_CMDLINE_LINUX param myself. I use grubby to add args, which has always worked when new kernels are installed for me.
