Switch Currency by JS with Cache Host

Hi there,
I’m using this plugin but everytime I have a new visitor, the product page is reloading (to change the currency). The problem is it’s hurting my SEO and ads delivery. I use a hosting cache (provided by Kinsta). Is it possible for me to make the switch currency by JS even if it involve some extra coding I need to do (I just need some path to follow in order to make it work). It is a necessity to make the JS switch working.

Thanks in advance.
