Not this type really, It's not something I would attempt, I'm sure there are those that do and certainly did do it without a jeweling tool. Friction jewels do need to be positioned accurately and set to the correct depth required, which is why the jewelling tool is used and was created, amongst its other uses. -
Here we go; this is the sort of info which transforms unknown unknowns into known unknowns. Never knew a cliche could be a physical thing, or heard of a pad printer. As for doing it by hand, that just sounds like, 'and then I do magic' to my ears...

My demagnetiser hasn’t arrived yet, but when it does, let me demag the movement and I will take another picture of the balance spring for some advice. Appreciate everyone’s help.

Great staking set! I have the exact same and love it. Congratulations on an excellent buy. Is the jewel aligning with the metal? If so, maybe you could. If it's not, there's no way you can control the depth of the jewel with the staking set. I've never used a staking set for jewelling, but I think I've heard others do it. But obviously, a Seitz or Horia jewelling tool should normally be the safer choice.

Hahaha, never a place where a Monty Python reference don't work, innit? Well, as @JohnR725 wrote and as @mikepilk diagram shows, 9010 is usually considered too thin for centre wheel and maybe also the slower of the train wheels. The issue with that is that it's easier for 9010 to creep away from where it's supposed to be. In my opinion (and lubrication is always contentious), an HP oil (mostly HP 1300, or D5) should be used on the centre wheel. And I usually use thicker oils like 9020, HP1000 or even HP1300 on the 3rd and 2nd wheel as well. But it's contentious. I have a service manual for Rolex 3135 and 2nd/3d wheel are HP1000, whereas a JLC 899 manual prescribes 9010 for those wheels, too. Escape wheel and balance always 9010. Anyway, if we focus on your specific problem of this watch which is rebanking (=too much amplitude): here we can either take a weaker mainspring or use heavier oils (i.e. HP1300) for the train wheels.
