Help with Viprion Vcmp and Thales HSM implementation

I haven't actually done it, but looking through the doco, it looks pretty similar to a standard NetHSM client configuration. I'm looking at https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-fips-thales-11-5-0/1.html

I'd been meaning to test that out. The one thing that I would think could be an issue is they are installing to a non-standard location, so NFKM_LOCAL will need to be set somehow. Presumably they do that. Are you having an issue doing it?
