UGREEN Thunderbolt 4 Dock 8-in-1 40Gbps TB4 Hub 3 x TB 4 Dual 4K@60Hz or Single 8K Display, 85W Charging, Gigabit Ethernet, 3 x USB A 3.2. Revodok Max 208 for Mac M1/M2/M3/M4 Pro/Max

I have been using this KVM for my 3 machines. I run a Mac mini M4 with it, my Gaming PC and my MacBook Pro M4. It works with three displays so it might be overkill for your setup, but I have been happy with my model and I believe they have one for two displays/two machines? https://www.amazon.com/dp/B0FC5PVXYD?ref=ppx_yo2ov_dt_b_fed_asin_title I also use the Green Thunderbolt dock to give me extra USB ports https://www.amazon.com/dp/B0CM2WKGLC?ref=ppx_yo2ov_dt_b_fed_asin_title, as well as a Anker USB C Hub that I have a few external drives plugged into. These all work great and I have been happy with them for the year I have had them.
