I’ve done some experimenting - I recommend that you just stitch. Please avoid glues and tapes it’s a road to disappointment for diy’ers and could be quite uncomfortable (eg tarp of bivy failure in the bush).
Most double sided tapes available retail in shops or online are not good enough, they tend to fail in use.
Tyvek tape (the real deal) is on its own not enough and is best applied for lazy seam sealing over stitches - it’s like a stiff tenacious tape thought
But good ol’ seam seal glue is lighter and better for sealing
Spray on glues only work if both sides are sprayed, which while great for bonding, is an absolute nightmare to handle
I can validate (unfortunately) that if you spray glue only on one side then bond, it fails in use quickly and completely - the tyvek just peels away
I strongly recommend that you sew. You don’t have to learn a flat fell seam, just a simple double roll with one stitch will do, and if you waterproof, some seal seal glue
Please also see the site ultralighthiker.com by a Victorian who has pioneered a few tyvek designs plus tests his work out for real in the bush - bit different to most YouTube videos by people who clearly have never put their ideas or post into practice and had to rely on them in the real world, because many just don’t work.
