Covid wedding and wedding registry

I wouldn't post the link on social media or anything like that, but it's ok to share the information directly with anyone who asks.

Do not post a link. Yes, that would look like you felt entitled to gifts, which is rude. But nothing wrong with making a registry, or , also, making a wishlist of items not registry ( available as a common item, like a picnic table, or bathsheets for the beach, or something many people might want to go in on.) You tell your family your registry link. You make sure they have your non- registry wish list. No one ever registers for firewood, but if you have a fireplace and woodstove. You let your friends and family who are motivated to give you a gift, contact your family. Or simply look up your registry on line. My first wedding, my FMIL cancelled. We eloped. But when returned, weeks later after a hiking honeymoon, friends of mine, where not one person was even invited to our original small 60 guest wedding that was cancelled, gave us a housewarming shower. And my extended family who were not invited originally, a huge family, about half sent gifts. And some of our school friends, graduated at our respective colleges, who had originally been invited, took up a no wedding collection. Which was just over a month's rent for the new apt for grad school.
And all my close family just gave us gifts. I know some people who have only received a couple gifts after an super small non covid wedding, or true elopement where the couple went away and married. But I know many more, who unexpectedly ended up with 30-100 gifts, many shower size, many wedding. As with us, although no one associated with either wedding, or family, should ever give a shower for some invited and some not ... If after knowing they are not invited, a group of friends or extended family wants to give a post wedding shower, or a housewarming, and invite others not invited to the wedding, that has always been okay etiquette. Just like in a full wedding, where a group not invited, your choir, or sports team, or co-workers, decide to have a separate shower, it is perfectly fine. What is rude, is when someone close to the bride or groom, invites others to give a gift. That is seen as asking those the couple did not care about not to invite, to give gifts. As long as the registry is there for people who ask for suggestions, the giver initiates things, so it is polite. And you can tell anyone who asks.
But you broadcasting it, or posting it, is seen as you giving people a push. Not at all nice.I hope a number of people will be happy you have married, and give you gifts because they wish you well.

I agree with pp if someone asked about it it’s fine to give to them directly

I would give people the link directly if they ask, but don't post it anywhere. It could definitely make people feel obligated if they see it.
