Section 4.3:

   The PTP protocols employ a distributed election protocol called the
   "Best Master Clock Algorithm" (BMCA) to determine the active clock
   master.  The clock master choices available to BMCA can be restricted
   or biased by configuration parameters to influence the election
   process.  In some systems, it may be desirable to limit the number of
   possible PTP clock masters to avoid the need to re-signal timestamp
   reference clock sources when the clock master changes.

So you can limit the masters in the normal way, that is, by
configuration of the masters.

Configuring a slave to choose a particular master is not specified in
RFC 7273.  Or is it (TLDR)?  If it is, then please point out where.

Thanks,
