That depends to be seen actually, Artificial Sacred Gears aren't real ones after all, Rizevim might not be able to nullify them. As to the Holy Weapon thing, i don't think Rizevim can nullify that but then again it probably won't be that effective against Rizevim, considering that Rizevim is just standing there doing nothing, when Issei and the others attack, and having Lilith by his side, Rizevim probably though there was no need to do anything against it.
