It's time for the reminder.
Robotech the RPG, had many other vehicles that I'm sure most GMs never even thought of using besides the Veritechs or Destroids.

GM, there is a whole world out there besides Pew Pew Me Mech that is so rich if you only open your eyes. pic.twitter.com/ezOVw5HuXm
*ahem*
NO ONE PLAYS MECHA GAMES TO NOT GET IN THE FUCKING ROBOT!
BattleTech understands the assignment; that's why everything other than a BattleMech is a deathtrap, and barring very specific situations you will lose if you aren't in a robot when the other guys in their robots come a-stompin'.
So no, there is nothing other than Robot Go Pew-Pew. It's like being in anything other than a Mobile Suit in a Gundam series; unless your name is "Bright Noa", you're fucked. It's why Star Wars is really about the space wizards first, the flyboys second, fleet commanders third, and everyone else a very distant Doesn't Fucking Matter (N.B. Andor/Rogue One is EXACTLY the DoomerPorn Bleakfic that Star Wars was made to combat, you shit-eating bugmen; Blake's 7 did that better decades ago on a shoestring and a prayer.)
There is a core premise to a game. Not fulfilling that premise is a Failure State. Saying "But you can not engage in the premise" is no different than saying "But you can smoke crack and fly by leaping off the roof" in that you're saying words, and even a coherent statement, but it's still meaningless gibberish nonsense that misses the point.
There ARE ways around this, but not in Conventional Play; for that you need to play the Real Game, and that's only possible in the Clubhouse.
