Switching to AMD after 12 years with Intel. Couple of questions!

Hello fellas, so I just got myself a brand new 9800X3D + B850 combo after being with Intel since the Sandy Bridge days. So naturally I have a few questions:

• What are some of the settings I need to be aware of inside the UEFI? Do I just set AMD EXPO and be done with it? or are there extra settings I need to tweak? (I do not plan on OCing).
• Chipset drivers? do I install the ones from amd.com? Do I need Ryzen Master?
• Windows power plan? with Intel I just kept it at balanced and it would turbo just fine during gaming, what about with AMD? I remember reading about AMD Optimized a while back.

Any help would be greatly appreciated.

Thanks.
