The right one can’t be wrong with me since it is not friction correct?
I assumed your was Shimano, which was an oversight on my part. I would imagine the Suntour are similar, but I am not familiar with them at all. Yes, you can trim (micro adjust the left shift lever to move front derailleur) to stop the grinding on the front derailleur, but you have to make sure to check to see if that is where the noise is coming from.
As others have suggested, don't use the front small chain ring for the smallest few rear gears, and don't use the front large chain ring for the largest few rear gears. That should avoid most binding on the front derailleur unless the front derailleur is out of adjustment.
