How to edit boot items of grub

[filo]

Hi there, welcome to the forum!
Give a look at this thread and relevant link.

Multiple Garuda boot entries in Grub after update

Meanwhile I found this: Gentoo Forums :: View topic - os-prober creating duplicate entry for main linux system TL;DR a partition can be blacklisted from os-prober so it doesn't show up twice perhaps on EFI there's no need for a GRUB entry, but I don't have EFI and don't know jack about it. edit: posting this just in case someone is still on BIOS booting, my previous comments were due to my misunderstanding that this case is about an EFI boot.

I think you could add /nvme0n1p2 to your skip list
PS: please always provide your garuda-inxi as requested by the template
