If fixing direct to the wall, then screws and plugs. If using battens,
then dry lining screws.

I wouldn't attempt to drill the walls at all.
The concrete is not very strong or thick on most of them.

I would make some angles out of builders band and fix it to battens and then
to the bolts holding the panels together.
it will give space to put some fibre bats behind for insulation.

Thanks, sounds relatively easy
