Can Lightroom Classic soft-proof using CMYK ICC printer profiles?

I’m preparing images for a lab that supplies ICC profiles for specific printers, but the profiles are CMYK. Lightroom Classic lets me soft-proof with RGB profiles, yet it won’t allow these CMYK profiles. Can Lightroom Classic still soft-proof CMYK somehow, or do I need to use Photoshop or InDesign instead? Is converting or reformating a CMYK ICC profile to RGB a valid way to keep accurate soft proofing?

According to blurb: Soft proofing and ICC Profiles in Lightroom, Lightroom does not support CMYK, and you need to hop over to Photoshop or InDesign to softproof CMYK. Apparently, use of CMYK ICC profiles was removed from Lightroom because they did not work reliably.

Lightroom Classic does not support CMYK soft proofing. If your print lab provides only CMYK ICC profiles, the practical solution is to soft-proof in Photoshop or InDesign instead.
Older Lightroom behavior around CMYK profiles was unreliable, and CMYK profile use was removed rather than fully supported. So there isn’t a proper workaround inside Lightroom Classic for accurate CMYK soft proofing.
Converting a CMYK ICC profile into an RGB profile is not a valid substitute for soft proofing. The profile describes the output behavior of that CMYK print process, and changing it to RGB would not preserve the same preview accuracy.
In short: use Lightroom for your normal edits, then send the image to Photoshop or InDesign for CMYK soft proofing with the lab’s supplied ICC profile.
