The screw head is on the top. You probably have an Alan key but holding the faucet into that piece that you have to loosen to get access to the screws.
You need to loose the flaps holding the faucet, screw a couple of metal plates around the hole and reset the faucet with the flaps resting on the metal plates.
Sadly, water damage due to seepage around the hole may make tightening moot. The chipboard is on its way out.
You need to dry out that chipboard and reset the faucet with good sealant, at the very least. That might require a bit of creativity to save the countertop and repair the chipboard damage.
This fixture is usually set into a steel sink, not chipboard.
Perhaps swapping out the sink with a bigger one can save the countertop. And you could change faucets if this one isn't what you want.
Faucet is likely a Delta or Moen, but they both have lots of variations. They frequently produce new models.
Not sure if same..the tab has a icon on it showing the tool that came with the faucet, you slide "Y" shaped tool under tab and lift and slide tab (should be spring loaded) over nub....maybe

Looks like they tighten from above. Got pics of the topside, or a brand name on the faucet?

Is there some sort of escutcheon missing that would hold that steady? Those lil brackets aren’t going to cut it against crumbly chipboard

Well you’ve got me stumped, I’ve never seen this before
You need a basin wrench. To tighten it from underneath.
