Every Pi model (2/3/4) does it slightly differently. AFAIK it is possible with all models.

An SSD just for booting? How often and how fast do you have to reboot your Pi? Booting from SD card is not that slow.

The best Pi setup for an SSD would be the Pi4 Compute Module and a carrier board with an M.2 slot. It uses PCIe instead of USB 3.0.

Like https://www.jeffgeerling.com/blog/2021/m2-on-raspberry-pi-tofu-compute-module-4-carrier-board

Not the cheapest solution though.
