TSAdaptChoose_Basic doesn't use the number of iterations (you can set your own callback for whatever policy you want), but TSAdaptCheckStage handles SNES failures and you can set a max number of SNES iterations. (This could be less efficient than a progressive function that gradually reduces time step as the number of iterations increases.)
