Não Pedro, When I look into my own build of the gdall dll I see no dependency on that “opj_encoder_set_extra_options” but likely because it’s a different version (I build from master).
From my experience on this there is really nothing one can do other than rebuild the dll or replace the dependency that is missing the required symbol. Nothing we can do from a conda installation. But ofc my analysis may be all wrong.

Did you manage to make it work in some way? I've already uninstalled a test PostgreSQL/PostGIS that I supposed to be the source of the conflict, but I keep having the same error. I also reinstalled conda, but nothing had changed.

I had and older Miniconda (Mini => 18 GB !!!!) that was so big that I removed and installed a new one in which I tried Pedro’s case and got exactly the same errors. I then run a dependency analysis from within the conda shell and found two weird things 1. The gdal dll depends on a xerces-c_3_2.dll locate at C:\WINDOWS\system32. This seems quite dangerous (for dependency sakes) but seems to not cause any problem in this case. 2. There is a “red mark” on the opj_encoder_set_extra_options symbol and this alone can explain the “ImportError: DLL load failed while importing _gdal: The specified procedure could not be found.” Hopefully the screen capture is small enough to get through.

But all of this sounds like there's something weird in your environment. Perhaps a mix of GDAL versions?
