arnold dome light visible in alpha with camera contribution 0

Hello,

 

I am doing some tests with arnold in solaris and realized that the dome light does show in the render alpha although camera contribution is set to "0". I can see it in the exr. I am rendering with husk using the usdrender_rop to output an exr. Is there somewhere else I need to be setting the dome light visibility besides camera contribution for it not to show in the beauty's alpha? 

 

houdini version:19.5.716 py3.9

arnold version: htoa-6.2.3.2_r6e449ce_houdini-19.5.716_windows

I did find why it wasn't rendering without the alpha in case someone has the same issue, in the parameters for camera visibility I was using 'set if exists' (assuming that because there was an initial value it would be an edit from 1 to '0') but it only worked once I change the parameter behavior to 'set or create' and set it to '0' then the dome would render without the alpha contribution.
