If you already have a HED 3 with a qr axle you can just swap the axle for a solid one and add some track nuts.
Depends which version of the road axle you have. The current aluminium axle can't just be swapped for a generic M9×1.0 axle. You can just use an Allen key skewer for track use. With the old steel hollow axle, you can tap it and use M6 screws and cup washers, as seen on upsidedown's TT bike.
