No specialist, but I think the construction method of my garage can be
described as "made of prefabricated slabs of concrete (?) joined

Can I drill holes on these walls so as to attach a trellis? The plant
to grow on it is a Lonicera Belgica.

In general, yes, but you may need to use bolts if the walls are very
thin. Always use washers or equivalent that are much larger than you
think you need, to avoid cracking the concrete.

Or you could scrub the relevant areas clean, abrade them, and use
epoxy resin glue.
