Look into unified kernel images (UKI). That makes you independent on a bootloader; whenever things go wrong (like Windows overwriting your Linux related entries), just use the 'boot from file' function in the UEFI firmware and select your Linux UKI to boot directly from that.

Arch Wiki is, as often, a great starting point: https://wiki.archlinux.org/title/Unified_kernel_image
