Probably yes.
I'm browsing TV channels around 17:00 (local time) yesterday and saw a basketball scene. That was on IBC13 and they are airing their news program at that time. They are now on the sports section that's why I saw a basketball image and that was PBA. As per the report, PBA will continue to All-Filipino once it resumed.
As bisdak mention, I doubt PBA will allow imports for now even let's say there is no travel restriction. Governors and Commissioners can be done next year as a fresh start. And besides, one conference takes 2-3 months IIRC including post-conference activity so All-Filipino is the only conference they can play this year.
