Disable cloudflare cache

I have doman that registered with cloudflare…
My domain DNS CNAME is targeted to “app.salla.cloud” because my store in salla ecommerce platform

I want to disable server cache compatibility from my site, and I tried all page rules :
Cache level : Bypass

But it didn’t work
I think because salla is registered with cloudflare… and they controll everything from his side
I told him that I want to disable cache… and they told me they doesn’t have this service yet

Can I disable Cashe from my side by adding any code inside my site ?
