If you can find a "TurnClampOn" output, you might try that instead. That appears intended to work with M10 and M11 to control a rotary table clamp.

So I guess I misunderstood how this function performs.
Since it only releases the brake, that really doesn't help the situation.

With larger parts, moving further from the CL of the 4th axis, the cutting forces are over coming the holding torque of the 4th axis motor.
I measured, with a torque wrench, and the addition of the brake results in 3x holding capability of the 4th axis.

The goal is to have the brake engaged whenever the 4th axis is not in motion.
M10 & M11 could certainly achieve that goal.

Manually editing the programs is doable, although, isn't ideal.
Maybe it's possible for the post to be updated, adding these 2 commands before and after an 4th axis move.

Is there documentation available for review for completing this change?
Generally, I can muttle my way through code, and get things to work if I have reference materials.....
I'd be happy to share the function once it's done.

Like Marc said you want the TurnClampOn output.
M10- Turns the output ON
M11- Turns the output OFF

So your pneumatic lock would be normally open or 4th axis UNLOCKED. Rotate it and then after the move, insert an M10 to turn it on, then allow the cut, then M11 to turn it off.

I ended up using the M10 & M11 gcode functions.
The Fusion 360 post by swissi actually has this feature, if enabled, it inserts all the code when generating the program.
Very awesome.
