Was wondering if it's possible to change the developer mode screen

Hypothetically can I change the chromebook developer mode screen on boot sort of seen here: Firmware Utility Script | MrChromebox.tech under Remove ChromeOS Bitmaps

Also, what would be the GBB flag to disable the beep sound? (source)

Idk the exact options but I think any non-stock GBB flags will disable the beep sounds. When I set GBB flags to do RW_LEGACY by default with 2s timeout, it no longer beeped. For “changing the screen”, @WeirdTreeThing has customized the screen on a Chromebook.

You can check out the exhaustive list of GBB flags here: GBB flag-inator

Thank you, once I modify the GBB flags by disabling WP, can I re-enable WP?

Figured it out, yes you can re-enable WP after
