It’s doable, but might not be feasible. ASUS used to offer a utility, MyLogo, which updated BIOS ROMs for their motherboards with a user-selected image file. Unless they or some hobbyist offer an equivalent… Maybe enabling fast boot will hide the splash screen?
If nobody’s documented the procedures though, you’d end up dumping the BIOS, probably end up using flasher hardware to update if they’ve made the update process more locked down (digital signatures and whatnot).
