Connecting a Display Port 1.4 graphics card to the Dell thunderbolt dock WD22TB4
Most monitors have a Virtual Control Panel (VCP), which implements features defined in the Monitor Control Command Set (MCCS). This is a VESA standard. You can find the Input selection command in table 8-10. You send these commands over an I2C bus called Display Data Channel/Command Interface which is yet another VESA standard. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar

Opinions on functional & performance requirements for a desktop TB/USB4 AIC
The protocol is called DDC , it's a VESA standard. In there, it's called VCP features. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar note how all three mention input selection.

TIL there are apps that can control your monitor without touching the buttons on it
ddcutil (a command-line tool, and what most UI tools are based on)

'monitorctl' cli tool to control brightness, contrast and volume of external monitors on linux
A related non rust tool (that also has an optional GUI) is ddcutil. How does this compare to that?
- I built a widget to adjust the brightness of external monitors

Brightness issue
I've also used ddcui: https://www.ddcutil.com/#introduction, available as an AUR package: https://github.com/rockowitz/ddcutil. This has a nice GUI: https://www.ddcutil.com/screenshots/ddcui_features.png and works on everything I've tried it on out of the box.

[Guide] How to unbrick Gigabyte G5 KC BIOS (step-by-step)
10th gen is locked by "Overclocking lock" And "Cfg lock" in bios, you can disable it thru ifr and use any software to undervolt your cpu (throttlestop on windows, linux has its own software (this, probably)). This is a lot safer than just putting voltages in bios as you can guess.

Help with installing intel undervolt on PopOS?
On Windows machines and laptops with Intel cpus, I almost always use Throttlestop to tweak power consumption and thus temperatures. I'd like to do so on this machine as well. I've found this: https://github.com/kitsunyan/intel-undervolt

Are there risks to setting a low CPU Multiplier (Laptop)?
I will try your suggestion about limiting power package. I've been using this 3rd party intel-undervolt software, which I'm not sure if it supports granular changes to wattage, but it seems like there is some energy/performance settings there.

bios undervolting
You can also undervolt though software on Linux based OS's. For intel there's these: https://github.com/georgewhewell/undervolt (this one looks more popular) https://github.com/kitsunyan/intel-undervolt (this is the one I use, no particular reason)
