UBUNTU 20.04 on Raspberry Pi 4/8GB, direct boot from SSD

This is more a question for UBUNTU developers...i think ?
Since Raspberry Pi 4 just made it possible to boot directly from SSD drive(via USB3),
instead of using micro SD card ...

It is fair to ask, when will be this possible with UBUNTU 20.04..

Do we need to wait for new version of UBUNTU..?
or this will be possible with some package updates/upgrades?

Hope for some direct answer(s)

Thank You so much in advance...!
