Any way to enable "Unlock Quality" on 1st play through? I did not select it from the grade shop at the start

Didn't select any grade shop options because I read that it ruins 1st play through.

Now that I'm at end-game and realize that the one option that is clearly should be enabled is "Unlock Quality" since it actually adds new stuffs to the game (rank 7 quality) without affecting much. I didn't bother to dualize equipment and the normal weapon works just fine but now I'd like to waste life away grinding for best stats.

Other non-toggleable option like exp x2, chain+, etc... are available from the dlc but this one option is not.

Is there any way I can enable this for my current play through? Cheat engine is fine if anyone knows how, just need to toggle this option on, or if someone knowledgeable about the save format and can hex edit it, I'm sure it's just a single byte

I was able to do it using Cheat Engine. Search for "Sora3100 Tales_of_Cheat_Tables". I can grind now
