Why can't Disney remake its old 2D princess films in CGI?

It's not that I hate the og 2d animation or anything, it is just I saw in a YouTube video (I forgot the source) said Disney "can't" remake their old princess movies into CGI versions, so they have to make live action remakes instead

So is it true? Then why Disney can’t made CGI remakes of their old princess animation? I'm 21, my first Disney princess movie in theaters was Tangled, and I've been a huge Disney fan since then. Based on my personal experience, I prefer to see CGI remakes than live action

The princesses‘ renders in Ralph Breaks the Internet are good, but it's still a bit different from the "Disney CGI style" after 2010. I would like to see the latter more
