If I cycle the key switch to off & on generally 6-8 times the light goes out for awhile but getting more frequent

Ran it on insite did regen
Everything checks out good
Kinda baffled

How about the SCR system filter? I hear they throw some wild codes if not changed regularly.
How many miles on the truck?

You have to put DEF in the truck correct? Or has it been deleted? The DEF is fed through the SCR system, there is a filter under there somewhere near the DEF tank, that needs to be serviced now and then, I would think at least once or twice a year. If not serviced strange codes pop up and can lead to further SCR system damage if I recall correctly. I have an older truck, no SCR system, just going by what I have read here and heard at Mr Hagg's shop and Rawze's house.
If you have a delete, I am assuming you do not, and are getting this SCR code, I would say you have other, possibly more serious issues going on, and need to have the programming inspected.
I wish I could be of more help, hopefully one of the guys with SCR experience will chime in.
