LCP file for Canon EF 70-200L f/4 USM zoom?

Apologies for posting this in the Lounge but I'm not sure of the best category otherwise. Please move it as appropriate.

I have a Canon EF 70-200L f/4 USM zoom. This is the non-IS original version of the lens. Per Adobe it's supported but I can't find its LCP file anywhere in the free DNG Converter installation on Windows 11. I know where to look -- C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\Canon -- it's just not there.

There's one for the IS Mk II version (Canon EF 70-200mm f4L IS II USM) - RAW.lcp) and another apparently specifically for the 5D (Canon EOS 5D Mark II (Canon EF 70-200mm f4L USM) - RAW.lcp), but I shoot a T8i / 850D. The others I found are for the f/2.8 version of the lens.

I've tried using the existing profiles but empirically they don't appear to do a very good job, not surprisingly. For example, depending on focal length they both under- and over-correct vignetting.

Are there any other legit / legal sources for LCP files?

Thanks.
