My W124 E 220's power steering pump needs a re-build and my car does not have SLS suspension. But I have access to a new tandem pump, I am planning to use it instead of re-building my old steering pump. What are possible ways to disable or block the pressure oil ( SLS ) pump. Below are the details and pictures I have collected.

The pressure oil pump is fed with SLS oil from a reservoir and pressurized oil exits the outlet.

Thank you

You don't want to run the pump dry. Just source the more common standard pump and use that. If you really wanted to use the tandem pump you should plumb both lines into a bottle of sls oil. Running the pump dry will kill it quickly, the power steering and SLS sections are separated internally.
