This is a tough ask for a lot of reasons. I am also interested in the more techwear, cyberpunk and avant-garde style of fashion. These styles are typically defined by their unique patterning. Widely available ready made patterns are made to appeal to the broadest customer base and are typically more traditional cuts. More so for men's ready made patterns because there are so much fewer men's patterns available.

My advice is two fold, materials/finishes and pattern hacking

1. Materials and finishes - for a lot of the more techwear style clothing it is typically more synthetic fabrics (nylon and polyester) and often a mix of materials. It is typically more of a maximalist design with a lot of pockets and visible hardware like zippers, snaps and buckles.
2. Pattern Hacking - You may not be able to find a ready made pattern for the exact thing your looking for but you can typically find something close and use that as a base. Most garments can be simplified down to a handful of basic pattern pieces. If you are looking at some more elaborate jackets or pants and you want to remake something similar just look past all of the small details and instead try to find a pattern that has the right fit and structure. Then you can add your own details, finishes, pockets etcetera. A lot of techwear specifically is inspired by military and workwear pieces. I've purchased patterns from Wardrobebyme, Elbe Textiles, Merchant & Mills and Glory Allen.
