Hi, why does not DFT-U include MGGA (MGGA-U)?

That would not be a well-established method and has not been implemented.

In addition, MGGA and GGA+U are both meant to get more accurate band gap and band widths for semiconductor materials. I think it would not make sense to mix the two approaches, unless there is a good argument for doing so.
