Lynchburg flip among other things suggests he might have.
Liberty was doing distance learning and liberty university is infamously bad even within the university of evangelical universities.
The Lynchburg flip was actually about decreased turnout on Liberty's campus. I think I saw that Trump was still in the upper 80s on what was left of Liberty's campus.
Plus, there's my general note that campus precincts aren't great snapshots to the views of a broad set of students. In my experience, few undergrads actually vote on campus, and the votes tend to get swallowed by professors/grad students/academic types. And, I could see a bit of a decline with those sorts of evangelicals (think David French).
But, I will say that I go to a huge young adults ministry of about 200 evangelicals in our 20s, and Trump had virtually unanimous support there, at least among the people who publicly discuss politics. If anyone there voted for Biden, they kept very quiet about it. Although, the Trump support is mostly not of the QAnon variety and pretty much everyone recognizes that Christ is King and Sovereign over all of this. I also go to another smaller ministry of about 15 evangelicals in our 20s at another church. In that one, the Trump support was probably more like 70-80%, with several not satisfied with either.
