Madison,
There is currently no rule that would prevent it. When this discussion came up a few years ago, we all did some searching and found several electrically operated regulators. Unfortunately most were designed for AC 24 volt controls. While we expected many teams to jump on the band wagon, we actually saw very few in inspections. I don't remember seeing any on the robots I inspected. I am going to guess that was due to either cost, complexity of control or additional weight. I know one team showed a servo attachment but the servo was not legal under FRC rules at the time. Please remember that all other rules still apply and one of those is the ability to release all stored pressure through one pressure relief valve.

[R77]
The pressure vent plug valve must be connected to the pneumatic circuit such that, when manually operated, it will
vent to the atmosphere to relieve all stored pressure. The valve must be placed on the Robot so that it is visible
and easily accessible. If the compressor is not used on the Robot, then an additional vent valve must be obtained
and connected to the high-pressure portion of the pneumatic circuit off board the Robot with the compressor (see
Rule [R73]).
