What do you mean by this? While the roboRIO has dedicated connectors on the PDB, they are not regulated outputs, they are raw battery. The only difference between using these connectors and a 20A breaker slot is the different protection (10A quick blow vs the 20A slow triggering auto-resetting circuit breaker)
OP, please explain what you mean by browning out? Are you actually managing to reboot the roboRIO? Or just trigger the brownout protection which disables your motors until battery voltage recovers? Have you checked how much current you are actually drawing using the DS logs?
I think you need to look at solutions to your gearing or software to manage your current draw. Putting a cap on the roboRIO input is both illegal (as noted by another poster above) and is kind of like putting a bandaid on a cut that needs stitches.
