I think hostapd configures basic and extended rates only. If you want
to force using MCS rates your best bet is iw utility.

"iw --help" yields this:

    dev <devname> set bitrates [legacy-<2.4|5> <legacy rate in Mbps>*]
[ht-mcs-<2.4|5> <MCS index>*] [vht-mcs-<2.4|5> <NSS:MCSx,MCSy... |
NSS:MCSx-MCSy>*] [sgi-2.4|lgi-2.4] [sgi-5|lgi-5]
        Sets up the specified rate masks.
        Not passing any arguments would clear the existing mask (if any).
