[REQUEST] MSI B350M PRO-VDH - BIOS LLC setting adjustment?

Original bios has terrible LLC settings and MSI is not going to fix it. Even the highest level results in -75mv Vdroop on r5 3600 under all core load… Cant add external link yet but it can be found here "msi(dot)com/Motherboard/support/B350M-PRO-VDH". Could anyone take a look or even point me to right direction? Thanks!

The board is practically identical to B350M Bazooka.
