Can we get a command or switch I can pass to "screen" on the command line to force the TERMCAP/terminfo to always be monochrome?

Why am I asking this?  Well, I want to put a status display up on a HP 100LX (which is connecting to a Raspberry Pi Zero with an Ethernet adapter via serial port cable).  It only does 2-bit greyscale (black, white, and 2 greys) because it's an LCD screen.

If I do the following:

1. set TERM to "pcansi-m"
2. run "screen -S test" on the Pi Zero
3. connect to the Pi Zero from the HP 100LX  (serial connection)
4. set TERM to "pcansi25m" (terminal does 25 lines )
5. run "screen -x test" on the serial connection
6. run "set | grep TERMCAP"

...and the "AX" capability is set. It should be cleared (not showing).  Color is wasted on the HP 100LX and screen (if told "force monochrome") shouldn't turn it on.
