Yes, that explains why it wants to pull in ocl-icd.

I'm hoping I've fixed it in the latest release. I've reverted previous 
changes and released updated packages to the testing repository. These 
should be available shortly (currently syncing to the mirror sites):

nvidia-x11-drv-340xx-340.107-3.el7_6.elrepo.x86_64.rpm
nvidia-x11-drv-340xx-32bit-340.107-3.el7_6.elrepo.x86_64.rpm

Hopefully this fill fix the issue with the 340.xx legacy release.
