Radio failsafe with skid steer

I keep getting a radio failsafe on my herelink controller even within a few hundred meters. While I figure that out I was hoping to get the failsafe working. Of course, the cube doesn’t see the failsafe and does nothing. I was hoping to use rally points in the event of a failsafe. This is a skid steer boat, so using a throttle setpoint won’t work lol. Is there another way to get the cube to enter failsafe so the boat will go to the nearest rally point?
