GRX-TVI run by RRD-6NA set to ELV/MLV/INC limit issues

My customer has some strange sconce lights by WAC WS-59623-AL light fixture that says it can be run via ELV or 0-10v. We tried to intially run with ELV and it wouldn't dim properly. So we ended up going fishing and installing the GRX-TVI 0-10V interface. FIxture claims it will dim 100-5%.Here is my issue, I have tired lots of things to get this series of 4 vanity lights to work to my clients satisfaction and so far it has been unsucesful. Currently Have low limit cranked to max 45% which has stopped the low end flickering but when the light switch gets manually set to 100% the light starts to flicker. Is there a way to set this top end to a lower MAX setting using the RA2 essential software. MR client uses the keypads and remotes and apps and fancy stuff 99.98% of the time, but MRS client hates technology and wants to walk in and hit the buttons all willie nilly all the time. Any Ideas

Thank you for your post PaulHagen.

Using the 6NA is not a problem, but we would recommend making sure the load is set to forward phase for the dimmer. This can impact how the GRX-TVI works with the dimmer. At the same time 0-10v is a standard and is not widely tested. As long as it is 0-10v it should work with the Lutron Controls. Hope this helps!
