Prestashop Expert - Speed optimizing - Litespeed

Hello!
I need help with speed optimizing my webshop. It need to be lightning fast.

Speed optimize Prestashop without breaking any function!!! (under 1sec)
This include everything, Core Web Vitals, optimization, configurations, image compression without loss of quality, host configure, cache plugins etc.
Everything should be trimmed for fastest performance!
(Disable unused plugins and modules and things that can slow down Prestashop.)

Remove all modules and things we dont use on prestashop to make it lightweight. Fastest possible.

Compare our speed with this prestashop websites that is kinda fast:
storkoksbutiken.se, novasolar.dk

---Our premium shared hosting server specs:
SSD
8GB ram
4 CORE
LITESPEED
APACHE
OPcache
REDIS
etc. (let me know if we need anything more).

---Speed test tools:
Google PageSpeed Insights (sweden) https://web.dev/vitals/
webpagetest.org (sweden)
GT Metrix (uk)

---I also got some prestashop performance modules we could use.

PM with what you can offer, and how you think you could help me.
