New PC, weird bios after install (sorry I post by accident last time)

[cscs]

@Some_Guy

you can open a terminal
sudo pacman -Rns plymouth;
sudo mkinitcpio -P;
sudo reboot

this should remove plymouth completely but you gotta mod the hooks in your kernel you boot from and remove plymouth. In dolphin or navigate there in cli go to root , boot, loader, entries if on sysd boot, if grub its just in boot folder, open with kate and in Hooks line for example heres mine, oop thats sysd only you can mod, grub encrypts files you cant mod and the mkinitcpio -P should cover it

Er .. not so much.

More like

• Packages
  sudo pacman -Rns plymouth-git plymouth-kcm cachyos-plymouth-theme cachyos-plymouth-bootanimation

• Mkinitcpio
  Remove plymouth from the HOOKS line of /etc/mkinitcpio.conf:
  sudoedit /etc/mkinitcpio.conf
  Then run:
  sudo mkinitcpio -P

• Grub
  May wish to remove splash from /etc/default/grub:
  sudoedit /etc/default/grub
  And update (refresh/reapply settings) grub:
  sudo grub-mkconfig -o /boot/grub/grub.cfg

EDIT

I copied and edited one of my older guides here that should be more full.

[Tutorial] Disable or Remove Plymouth (boot splash)

Introduction CachyOS ISOs provide and enable plymouth by default. From the ArchWiki: Which is to say it is not a system-critical component.* It also has a nasty habit of breaking boot under various circumstances. In those cases, or simply to avoid the bloat, you can temporarily disable plymouth, permanently disable it, or remove it entirely. * - Some systems use Plymouth to forward decryption prompts. This may be especially useful in cases where the language and input devices might differ.…

@Some_Guy

the -Rns is a special flag that makes sure it dont break any dependencies

Also not true.

-R is remove.
-n is include ‘save files’.
-s is also select dependencies not required by any other package.

See man pacman.
