You can currently use Forward or Backward differences. But only first order one-step methods are implemented.
Higher order time one step multi-stage time discretisation methods sort of work on an experimental branch (track https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/issues/940 <https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/issues/940> for current status) and some components have been merged but it’s going to take some time to make it into master.
