Concurrent Parameter Disable

Question

Hi ,
I have one parameter PARAM1 attached with a custom Concurrent program. This parameter basically takes an input like 'Yes' or 'No'. This concurrent program also has another parameter PARAM2 to process purchase orders. Now if we don't pass any value to PARAM2 then the program will run for  bulk data. But if we want to pass any value then we will need the PARAM1 to process it manually.
My question is how to Disable the PARAM1 while the concurrent program is running for bulk data. I want to avoid human error so that when the program is running for bulk then it should not give you the option to provide data in PARAM1.
Thanks

Based on this requirement "if the value of the param1 is null then the param2 should not appear", the following can be achieved:
- Have PARAM1 accept Yes/No/Null as values
- Enable PARAM2 for modification only when PARAM1 value is not null, clear if PARAM1 value is cleared
