They are low profile cards, use up to 75w and no active cooling. While the 7040 MT has enough power from 240w power supply, the SFF has only 180w PSU but they will fit.
As intended to use in rack servers, the Tesla P4 if working at all, it may not run at full potential due to lack of airflow to keep it cool and unavailable lanes bifurcation features from the 7040s.
Until you can get pass these hurdle, the OS should recognize and allows integrated or dedicated GPU to access its engine and memory as similar accelerator setup have been done and worked with the larger Precision line.
I wouldn't trust 75w GPU on a 240 watt PSU. Unfortunately, the 7040 comes from a generation of low-watt PSU's making upgrading more of a challenge. Adding to the challenge is the tower not being a full-size mini tower.
There's the spec sheet I attached with suggestions. Also, other lower watt LP cards can also work: 30w GT 1030 GDDR5; 30w Quadro P400; 50w RX 6400 (MT)
Airflow isn't a problem since I 3d printed something that forces airflow through a tunnel into it from a 40mm fan. I downloaded the proper drivers and the OS recognizes it and the device manager shows it as a display adapter, however I don't know where to go to force it to use the P4. Will it only use it if I set up vm? I'm obviously new to this, but my son and I never shy away from a project. I have 5 7040s and would love to deploy them as power work stations at my small office... I've also given one to my son and he'susing it for when friends come over to game, but the card in it right now is the r7 350 which isn't the best.
It's great that the OS recognizes the card as you will need the nVidia control panel, next step would be changing Tesla driver to graphics mode. This tutorial guide may walk you through the rest.
Usually, the control panel would be installed automatically after the driver. Uninstall the current driver, restart machine and let Windows install the correct driver. You can also run Windows update to install proper driver.
Instead using power shell, you can try regedit (from linked video) to add direct X and changing Tesla driver to graphics mode.

So it was working great without the Nvidia control panel? May need to uninstall.
