HELP TC-895-EB11 - New 2666MHz RAM running @2133MHz

Options
Hello Community

I recently upgraded the 12GB RAM on my PC to 32GB Corsair Vengeance LPX CMK32GX4M2A2666C16
The stock RAM was:
Kingston 8gb 1rx8 Pc4-2666v-ua2-11 Ddr4 Desktop Memory 9995702
Kingston 4gb 1rx4 Pc4-2666v-uc0-11 Ddr4 Desktop Memory 9995665

After installation my RAM is only running at 2133MHz as shown in Windows 10 task manager.



I see that Acer has a BIOS update that may allow me to enable XMP here but there are no release notes so I am hesitant to try.

Anybody have this BIOS version?

The Comet Lake chipset supports 2666MHz.

Any ideas to get me to 2666MHz?
Am I stuck at 2133MHz with this motherboard?

Thanks in advance!
