x96max q1 s905x3 u-boot usb disabling

Hello, I want to use ssd over usb3.0 hub, but i got usb3.0 init error, when u-boot trying to init it for booting.

What is the simplest way to disable usb3.0 init on u-boot?
If I need to recompile u-boot for my device, what is the simplest way?

Also, I can boot armbian from mmc only when install with mainlain flag was used. It's confusing.
