Can the latest version of RTKLIB demo5 decode HAS corrections from Galileo's E6B signal? Does it support the HASPPP service?

I recently have a Ublox X20 receiver, and I wish to test the PPP performance of this receiver under the HAS service.
If this software supports it, or if you can offer any suggestions, I would greatly appreciate it.

There does not appear to be any particular support for HAS in RTKLIB. Might the X20 have support for global PPP built in, and might this be configured using the ublox tools?
