ok lol dumb question...

Yes, as long as the CDN you use support them. I used to upload mine on satellite.earth.

The other way I also used was to upload to nostr:npub1stemstrls4f5plqeqkeq43gtjhtycuqd9w25v5r5z5ygaq2n2sjsd6mul5 and then lift the link from there. But it doesn’t play nicely in all clients.
