Stop iCloud Drive from taking up hard-disk space

Is it now possible in 2022, using Big Sur, to copy files into iCloud Drive, and have them stored only on Apple servers / in the cloud, and not on my Macs local hard-drive?

I understand I can 'Optimise Mac Storage', but I have just enough space, for the full contents of iCloud Drive to be stored on my Mac.

I don't want these files stored on my Mac, but in the cloud.

Is this now possible?
