Pharo 9.0 warning message on starting - "The current VM does not support TFFI Callbacks."

Question

When I start a Pharo 9.0 x64 image with the Pharo 2.2 Launcher on Ubuntu 20.10, I get the following warning:

The current VM does not support TFFI Callbacks. It will use the old implementation.

I assume this is a reference to threaded FFI being added to the VM in the near future. Is there a way to use a newer VM that supports TFFI?

The only other post I could find on the internet relating to this warning is this one.

Thank you so much for reading this!
