The conversion must be done in Photoshop. Lightroom doesn’t provide custom profile options when exporting, just standard RGB color spaces. You can export to a custom profile in Lightroom Classic, but the profile name you mentioned sounds like a CMYK profile, and Lightroom Classic doesn’t support CMYK profiles. So that won’t work either.
I'm not the most technically up-to-date person, have never claimed to be. What type of profile is it that you are referring to? As you are probably aware, if you are attempting to export a raw image as an original from Lightroom there is no choice at all for profiles. If you are exporting JPEG then you can choose one of the RGB settings or a display profile, but that is it.
