Can I delete third party mods on ps5?

So I went to use the cross-save feature for Baldur's Gate 3 on my ps5, and was exited to try it out. Unfortunately when I went to actually play the file, it told me that I couldn't because of the fact that there were third-party mods. The mods don't really have any real use (for the save) as it's just two classes that I haven't incorporated into any of my characters. It won't let me delete the mods or anything for some reason, it just gives me the option to leave that screen. Is there any way to fix this not using my pc?
