Yes, but by default binding to an IPv6 socket also binds to the IPv4 socket.

From the IPv6 man page:

       IPv4 connections can be handled with the v6 API by using the
       v4-mapped- on-v6 address type; thus a program needs to support
       only this API type to support both protocols.

Did you try binding one ptp4l to IPv4 and one to IPv6?
