I have a question about my PS4 memory ?

So we all know the PS5 will be coming out soon. I want to get the Digital Edition, the one without the disc drive. I’m concerned that if I get the Digital Edition, meaning I can’t use discs, that I will lose add-one I got from the disc. Now I know that add-ons can show up in the library game menu, and I believe hard copy games cannot but that may be wrong, please inform. My main concern is my hard copy of Red Dead Redemption 2 Ultimate Edition, it has two add-ons that really help out the game experience, well it’s the Ultimate Edition add-ons and the ore-order bonus because I pre-ordered it. I don’t really play any of my hard copy games anymore except for RDR 2, and I have no problem re-buying some of the hard copy games in digital versions I don’t play but still enjoy, like Alien Isolation. Thanks for any help!! I don’t have an issue with the regular disc version of the PS5, I just think the Digital Edition looks really cool.
