Reliably ? Not at all.

If you were desperate, you could loop some copper wire around the pins and tie tight.

Just buy a soldering iron man.

I saw a review on YouTube about Convoy S2, there is described a method of switching from the first group (5 modes) to the second (3 modes).
If the driver can not so, tell me what to choose

What are you planing on driving ?
What current do you want ?
What is your power source ?
What host ?
What size driver do you need ?

Myself, I'd buy a Nanjg 105c (SKU 1186301) and remove 4 of the AMC7135s.
