IVIG infusions and Keytruda infusion compatibility

i am currently receiving IVIG infusion, 60gm Gamunex-C, every 3 weeks.  i was recently diagnosed with kidney cancer in left kidney and have had it removed.  Pathology report identifies my Stage/etc as: 4ccRCC / pT3aPN basically stage 4.  Oncologist is proposing Keytruda infusions every 3 weeks for one year.  Since Keytruda could initiate GBS, discussion regarding impact, plus or minus, of doing both infusions.  My research indicates that the Gamunex infusion is a positive in that it helps to minimize that GBS initiation and has no negative effects on the performance of the Keytruda.

Do you have information/studies regarding doing both of these infusions and their compatibility?

Thank you
