Connect both hall and incremental quadrature encoders

Hi, my BLDC servo motor has both internal hall sensors and an incremental encoder (see info below)

Can I connect both sensors to Vesc (4.12 HW)? Hall sensor is clear but how do I connect the quadrature encoder (to P3)? It's just A,B,Z no SPI.

Can I use the hall information for initial positioning and then go with the more precise incremental encoder?

I must avoid an index search on startup as that would move a big robot without control.

Cheers
