New Build Guide for VyOS rolling?

Hi VyOS team

I found my usb wifi didn’t have driver in VyOS and I found the FRR deb in VyOS has bug with OSPF
So I want to rebuild kernel with mt76x0u driver and rebuild FRR

But vyos-build will pull deb from VyOS pre-built repo
So is there any guide to patch for kernel and frr binary blob?
