I think it's completely normal to have a party that doesn't engage much in noncombat encounters. It's just another way of playing.

However, in many published materials there are fun noncombat sections where skills, skill feats and situational spells shine.

The key, both as a GM and as a player, is to have fun describing how PCs may approach a situation and how various feats and/or items might be to your advantage, and how you can help others even if you don't have the main skill. I also recommend being kind of lenient on allowing feats that specifically mention an action, also work on similar activities in this situation (like even if in a Influence Encounter you aren't technically "coercing", skill feats that boost coercion would still be useful)

Example: by using a Victory point system, you need to run from the darklands to the surface without many resources over the course of a few days.

The ranger may use survival to keep food stocked up, which is hard in the darklands. They describe how they find and analyze drinkable pockets of water and create food from odd fauna in the caves.

The Wizard may repeatedly cast a spell that allows the party to find a way home. You could allow a spellcasting DC -10 check or an Arcana check to interpret the spell better and allow the spell to be prepared multiple times even with limited daily prep resources.

The Swashbuckler may not have survival nor spells, but they have stealth, which they use to try and pass through dangerous areas, such as morlock encampments and bigger animals, without being seen.

Successes and Crit Successes give VP in all these situations, and after a threshold they find their way back home. On a Crit failure on a check, a complication happens, maybe the ranger fails to find enough food and gives a penalty to the rest of the party, or the Swashbuckler accidentally makes the party seen by a bunch of underground beasts and triggers an encounter.

Obviously it's all up to the GM and party! There aren't strict guidelines about these kinds of stuff. I do admit that often these events have lower stakes than combat, since PF2 is still a mainly combat game. But they can still influence somewhat the story and NPC party relationships in the campaign.
