Lecturer here.
Do this logically.
First, he needs to contact the relevant people at his university to find out what is possible for his course. Is there a fully online version? You mention that one class is "practical hands on" - does that mean literal hands on? Would he need to change modules? By this stage of the semester, module changes tend to be allowed only in rare circumstances - but given Covid, it may be that universities will be more relaxed than usual in relation to changes. And finally, if he wants to resume F2F teaching this academic year (say in January, because some miracle happens over the next six weeks), would that be possible?
Second, what is the university's response to lockdown? FWIW, at my university, a decision has just been made to move virtually all teaching online, with an exclusion for practical classes. This may impact on the answers to the above questions.
Third, you need to think about his mental health and what will be best for his studies. If he is miserable, isolated and anxious, and doesn't see that changing during the coming lockdown, then it doesn't really matter that InsertYourUserName's son or daughter feels differently. And I should add - I have seen some very distressed students. We have also had quite a lot of students who originally requested in-person teaching now asking to be moved to online groups.
Finally, if he does come home, please remember that he might be bringing Covid with him, and you should act responsibly to your local community by taking extra care with quarantine (over and above what is mandated in lockdown).
I hope this helps.
