I tend to side with MikeS here, forward-only addresses are generally
only provided to catch any mail still sent to them, so the senders can
be informed of a changed email address.
If your uni would have wanted you to keep using that address they would
have provided you with a real account.

So far you could use your uni address as a fake address on the SMTP
server of your provider.
Proton mail will not allow that, it is a trick very often used by
spammers and worse, they obviously don't want any of of that.

FWIW, my ISP does allow it, so I could test it for a few addresses.
Email sent with fake email addresses does arrive, but only with
addresses from existing domains and always with internal warnings which
could easily trigger a spam or phishing filter.

So, long story short, it looks like you'll finally have to bite the
bullet and inform your contacts of your new email address.
