Can you deny a critical role?

They tried to get me to train in robots a month or so ago. I talked to my AM and she got me out of it. Now this week they’re trying to catch me again. I don’t wanna go to my manager again. So I’m curious if I can personally say no to the learning people? Would it be insubordination?

(11month seasonal, I’m not taking on a critical role until I get my benefits and vacation time lol)
