I can speak to one instance of this (which was before COVID and the events surrounding George Floyd, so apply context as needed), but I took a class on networking implementations in low-budget and rural regions.
As part of the curriculum, there were distinct lessons (in this hard-science course) on feminist design, avoiding white-savior rollouts, and cultural relativism -- with much room to expound on their importance, and little room to critique.
I happened to agree with lots of the mindsets of these lessons a priori, but I was definitely acutely aware the whole course that there was an ideological bent, even in STEM.
The networking stack obviously had no viewpoint, but the course teaching it certainly did.
