I have a Lenovo V15 G4 laptop that I want to overclock

I had to pay some guy $50 to teach me a little bit about overclocking this laptop.

So I wanted to know if you guys are able to explain some more or help me fine-tune my settings.

Max supported add-in RAM was listed at 8GB. So I threw in a stick of:

G.SKILL RipJaws (F4-3200C22S-16GRS) 1x16GB DDR4 SODIMM 3200MT/s CL22-22-22-52

https://www.amazon.com/dp/B08J2WGSRZ

Worked perfectly fine on the first boot, all the RAM is addressable and stable (I've ran hella tests, haven't have any issues.)

After this guy I paid unlocked my BIOS, I was able to access RAM advanced settings (unfortunately, there are no CPU overclock options, idk if my BIOS needs some more editing or the options just aren't available :/

My max timings are: 18-19-19-19-31-50, but this crashes some times & Apex Legends constantly kicks me out lol

My current timings are: 18-20-20-20-38-52

I used this guide for my calculations:

How am I doing so far? And can I get some help unlocking my BIOS, please and thank you:
