I think it's experimental, i.e. you may have to experiment and it may not work for all scenarios.
According to the official documentation:
It is not supported _yet_ for Pi 4 but will be available at some point.
However some very recent articles on other sites seem to report some success (and some failures):
If you can't get it working you may have to sit it out until it is more hardened or better documented (on an official site).

Addding to what Shabas has mentioned above.
RPi USB boot is under beta testing now. But you can still test it out. It's mentioned that It wont work for all MSDs.
About network booting.
There is a hackaday post on booting RPi4 using PXE (With a bootloader upgrade).
Check it out here: https://hackaday.com/2019/11/11/network-booting-the-pi-4/
Hope this helps.

NGU, texadactyl did a recent post where he provided a reference to USB boot that he said worked for him. I don't want to take any of his credit for the post he made in Alsa no audio (glitch) issue Pi 4 fix He provided the following link https://tynick.com/blog/05-22-2020/raspberry-pi-4-boot-from-usb/ I bookmarked the page because it is something I might try.
It worked perfectly with Raspbian for me. Subsequently, I moved on to Ubuntu 64-bit so I am going to wait for the Ubuntu release to catch up (they have pressure!). In the meantime, I am keeping the MicroSD installed just for the boot.
Ubuntu Server 64-bit with the Xubuntu desktop is excellent. Highly recommended!
Great follow-up RE. I took note of your post and had hoped you would chime in for NGU and provide some commentary.
