In The Bad Batch episode "Battle Scars," the Batch must break into an abandoned Venator-class Star Destroyer in order to utilize its medical facilities to remove their chips. This is noted to be risky but the only available option. It is beyond reach of the medical equipment possessed by Tech.
This process also requires the technical/medical abilities of Tech, as well as his specially made brain scanner.
This event, combined with the fact that there is no evidence Wolfe or Gregor had a Jedi help them, leads me to the conclusion that the Force is not required. However, advanced technology and some degree of medical skill is.
