If clutch is non stock, is better asked from previous owner of car.
Simplest to ask about clutch pedal helper spring aswell from previous owner, if it's stock or removed. But you can also see it for yourself in pedal assembly. Visual check won't work much if spring is there but of different spring rate though.
As for mod,
clutch cylinder swap thread,
clutch spring removal thread. Except take note, that:
1) these mods are for opposite, to make pedal even firmer, not lighter to press. Hence part numbers mentioned in first won't do for you. Different master and slave hydraulic cylinder diameter ratio .. think of that as different lever length. One can make shorter travel but more force required, or longer travel and easier to press (stock). And regarding second, most often varieties of that are complete removal of helper spring, or installing softer sprung,
mtec spring, somewhere inbetween stock helper spring and no spring at all. Stock spring is firmest, so it assists clutch pedal press most (dulling feel in process). Mtec assists less, no spring - firmest pedal feel. I guess, you may want easy to press pedal, thus firmest assist spring. Seen people reversing mod by reinstalling stock assist spring when installed much stiffer aftermarket clutches.
I also guess, that if you find similar sized but even firmer spring then stock's, it might be even easier to press. Not sure. Noone did opposite

2) IIRC it might be more PITA to deal with this
spring mod on RHD cars such as in UK. Mine is LHD, so no issue, but probably worth noting.
3) stock spring is very stiff. PITA to compress/reinstall. And be careful with E-clip. Easy to break/loose.
