What are all these voltage settings and should I change any of them besides CPU Vcore? (i5 9600k)

I'm trying to overclock my i5 9600k to 4.8ghz and read that I should have the voltage set to around 1.35v-1.4v. I'm just wondering if I should be adjusting all of these settings individually or if I should leave them on auto and only change CPU Vcore?
Thanks
