WOO! I figured it out thanks to this old video from Carmen & Ingo Photography (https://www.youtube.com/watch?v=bMNemLondeQ)
Step by step for others who might be looking for how to convert old VSCO desktop presets to work with canon eso R5 and R6 cameras in Lightroom:
1. download a Hex editor for mac if you don't already have on one your computer. I downloaded Hex Fiend from the app store for free and it worked great.
2. Go to where your VSCO presets are stored currently for Lightroom. For me (and probably most folks) this location is HD>Users>[Your User Name]>Library>Application Support>Adobe>CAMERA RAW>CameraProfiles>VSCO Film 00 Canon Profiles
*note* your location might be a little different and many folks have all the VSCO presets dumped all together into the CameraProfiles
3. Look for the camera profile version for the CANON EOS 6D in this example I'll pick the profile titled "Canon EOS 6D Kodak Gold 100 - C.dcp"
*note* not every preset or version of a preset will have it's own camera profile. Many VSCO presets and versions are built on the same camera profile. So for this Film Pack 00 there are about 32 preset in Lightroom's Presets panel (in the Develop tab) but they're all built on the base of just 3 camera profiles.
4. Create a folder on your desktop to store a copy of the files we'll be working on. Copy and paste "Canon EOS 6D Kodak Gold 100 - C.dcp" into the desktop folder you just created and change the name from 6D to R6 (or whatever name you want it to show in Lightroom. This will not change the actual file at all)
5. Open the Hex editor program and you'll see an empty box. Drag and drop the "Canon EOS 6D Kodak Gold 100 - C.dcp" file onto the empty Hex editor box.
6. You'll see a whole bunch of numbers on one side and mostly special characters on the other. Don't freak out, it's supposed to look like that.
7. Hit command F to open the Find/search box. On the right side of the Hex editor you should see some text among the special characters that says "Canon EOS 6D".
8. In the Find/search box type in 6D and the search or next button.
*note* Make sure you use the same capitalization in the find/search box
9. On the right you should see that the text 6D is highlighted and the 4 corresponding numbers on the right are also highlighted (in this case the highlighted numbers are 3644 followed by several zeros that are not highlighted).
10. In the REPLACE field of the search box type in R6 and hit the REPLACE button.
11. This will replace the 6D text and corresponding hex numbers to the R6 hex numbers.
12. Hit command S to save (or File>Save) and close the file.
13. Drag and drop (or copy/paste) the edited file from the desktop folder you created earlier back into the CAMERAPROFILES folder with all the other VSCO lightroom camera profiles.
14. Open or restart Lightroom.
*note* you must restart lightroom after moving the file for it to show up
15. Throw yourself a damn party cuz you did it!!!!
I think this should probably work for any .dcp camera profile not just vsco so if you have other old presets or, like me, the custom presets you use on everything were made via a thousand tweaks from other older presets.
