I tried letting some water sit for some hours in one dent, to see if the wood would expand - but nothing happened. I guess that would rule out steam, unless I remove the varnish in the dents first?
Water alone won’t help much, using steam can. Putting a damp towel down and using an iron over the problem areas can sometimes affect the dents a variable amount.
Depending on how good the varnish is, that will determine how well it works.
Steam might be able to fix those. But I don’t know if that would work with varnish on the wood.

That sounds like a fun thing to improvise, thanks, I’ll try it!
You have to remove the varnish by sanding first, then try to iron the floor. There may be poor contact in the middle so try ironing the other edges.
Other than that, you are gonna have to get new boards installed.
Yeah, OP wants to work over a large are, not just where the dents are.
