Boot from emmc on Raspberry Pi 4B

Can volumio boot from emmc on Raspberry Pi 4B?

Raspberry Pi 4B does not have EMMC

Maybe he mean this.

I had success booting a Raspberry Pi 3 from an eMMC put on those (above) kind of adapter. I used to standard ISO file method.
Raspberry Pi 4 should not be different

This SD-eMMC card should work too, I want to try it.
