You can disable it by radxa utils rsetup.

rsetup: overlays -> Manage overlays -> Disable HDMI.

No Sorry, i dont Need to disable HDMI, i need to configure zero 3 without hdmi with pre boot configuration

The most simple solution would be to use an USB to serial adapter. They are rather cheap, allow you to debug later on and, if you don’t plan to add energy hungry devices, can power your Zero directly with 5V.

Attention: Do not and never ever buy one with a PL2303. They are crap! I have learned the lesson myself. I use CP2104 and CH340 and they work fine.
