Thank you! I was missing that.
So, those are the steps I took for the noise profiling:
1- I use WSL (Ubuntu 24.04.1 LTS) instead of a virtual machine. And I compile darktable (full install)
2 - In step 2 of the guide mentioned by @MStraeten, I run /opt/darktable/libexec/darktable/tools/darktable-gen-noiseprofile -d $(pwd) instead of /usr/lib/darktable/tools/darktable-gen-noiseprofile -d $(pwd), as mentioned by @da-phil in another thread.
3 - Follow the rest of the guide mentioned by @MStraeten.
I just submitted the noise profiles created on darktable’s github, here.
For lensfun:
I edit the corresponding lensfun xml file (mil-canon.xml) and create another entry by simply copying “Canon R5” parameters and adding a " C" in the end.
The xml file was located in C:\Program Files\darktable\share\lensfun\version_1
I hope this will help someone in the future!
