yes, configure each vesc individually to its motor, and run a y split servo cable from both vescs into the reciever. also make sure you cut one of the 5v wires so you only have 1 input of 5v from the vescs.

Setup both with the vesc tool, honestly I think the CAN is broken on at least one as when I try the command can_devs on the aster it doesn’t appear to be able to see the slave
