I use rEFInd as my bootloader, but I have ubuntu's kernel inside an lvm logic volume, so I use GRUB to call it from refind and boot ubuntu. But every time I update GRUB (via apt or update-grub) it sets itself as the first boot option, and I was wondering if there is any way of avoiding it, either editing some post-update or post-install hook or may be with some configuration option.

Thank you so much and sorry if I have been impolite, English it's not my native language

You might be able to patch /usr/lib/grub/grub-multi-install to add --no-nvram to the arguments of grub-install. The postinst scripts for several packages call grub-multi-install.

I dug into this before on this Q: How do I get grub-efi-amd64-signed to not automatically overwrite NVRAM on update
