Is it possible with nostr:npub1rky9qeplwklrsezde4nrzy4qqtr0fasvhhauqdjrd8ej44uxerfqjn0xq2 to follow the public timeline of an instance that you're not a member of?

e.g. i'm not on front-end.social, but if i want to follow their public feed — https://front-end.social/public/local — somewhere in Ivory, can i do that?
