Install To Hard Drive

My reading of the install/flash instructions has me thinking that Volumio only works from an SD card that is permanently attached to the target device. No?
I have a fanless mini computer that I use just as a music server. It’s a partaker and almost identical to Volumio’s Mini86. Is it possible to install to my M.2 hard drive?

Yes, go to system settings -> install to disk

Thank you so much.
And so, I begin.
Will keep you posted.
