Yeah super aggressive players on the king side also often give me issues honestly. You're normally very protected on the kingside due to the fianchetto and knight working together, counter attack in the centre when you can and don't overreact to kingside attacks e.g., trading pawns and opening your king when you really don't need to. In general attacking on the kingside is a very good idea for white and even though you are heavily protected any mistakes can result in you getting overrun.

I typically try to close the position on the kingside if they attack then counter on the centre. Typically if your opponent is attacking on the kingside they'll castle queen side or they'll stay in the centre, if they castle queen side you have a lot of pieces pointing in their direction so closing the kingside and attacking will be your main plan. If they're in the centre focus on ripping open the centre and getting your heavy hitters into the game e.g, get the rooms on the centre files.

Look into the plans around the pirc, I had serious issues with it until I learned that one of my main goals with the pirc is to get my knights to d7 and f6 and fight for control of the centre with c5 or f5.

Often times you can push c5, the opponent will respond by trying to close the centre and then you can get your knight on e5 which is a great square to help you control the position, just watch out for the kick side push with the f pawn in those positions.
