I'm not qualified spiritually to speak on this, but I think that this should actually be "kosher" - since the PVC didg would lack some of the manufacturing processes like burning the inside and bees waxing and etc A -- to not make it a "true" didg but rather an instrument that sounds like one

I’m at least as unqualified as you but I suspect you making a good faith effort to play it is better than the world-traveling boomers I know who bought one as one more third-world artifact to decorate their home. 🤷‍♂️ (This isn’t saying much.)
