Is there any way to remove the dimmer function and have the 2334-222 be on/off?

No. The dimmer uses a triac and the on/off uses a relay.

Its too bad the stopped making the on/off 8 button keypad....cant seem to find an old one on ebay either. 

The 6 and 8 key versions can be switched between 6 and 8 with some setup key presses. If you have the screw on 8 keys part or have an old one lying around you could get there

Im not following.  Are you discussing a model other than the 2334-222?

You can change the 6 key facia on the relay keypad to an 8 key:

• buy a new 6 button relay (on/off) keypad from Insteon when they're scheduled to be back in stock in January
• Remove the 8 key keypad facia from your existing  2334-222 dimmer key pad and screw it on to the new relay keypad
• Look around page 16 of the Insteon keypad manual.. there are the directions for reconfiguring the new 6 key relay as an 8 key relay. The manual details all of the steps described above

🤯 I had no idea this was possible.  That is amazing.  Even better that it could be done with a device in place. WOW thank you.

Want to come back and say I followed the suggestions of paulbates and it worked 100%.

Thank you!
