boot order i was setting up in bios

i have found some forum post

https://www.reddit.com/r/NixOS/comments/133fkp7/grub_with_nixos/

And i have found garuda forum post on systemd boot that you @SGS have provided some answer

ok so what i have found, is to remove grub and replace it with systemd-boot

also found that maybe Leo user could help me with replacing that grub
