Is it possible to take minecraft store texture packs and use RTX converter?

I want to use the Fallout Mash up textures, however I cannot find the file anywhere on Windows 11. Is this possible?

Hi, no that's not possible.

Even after you find the files for Marketplace packs, it won't be possible to convert them using the app, since those files can't be read or edited.
