Reduce P-1 memory bandwidth used?
 
Is there an option to reduce the memory bandwidth used in P-1, even at the expense of a slower test?

Your question lacks necessary context. Which program(s) are you running P-1 tests in?

What are your memory and other resource settings? (in prime.txt and local.txt)
And why do you want to limit the bandwidth? Would pausing mprime while running another particular program be helpful or the solution?
