It is quite possible that G.Skill Aegis (2x, 8GB, DDR4-3000, DIMM 288) Manufacturer No. F4-3000C16D-16GISB
could work. MSI only tested the Aegis series up to 2400MHz. G. Skill has developed the series up to 3000 MHz.

MSI tested the Trident Z series up to 3200 MHz for the B450 Gaming Pro Carbon AC.

It depends on whether OverClocking up to 3000 MHz is planned.
When overclocking, it is also important to ensure good heat dissipation with the RAMs. Note the dimensions of the bars.

Is a further expansion up to 32 GB total planned?
