Shared hosting whitelist cloudflare ip

Is there any hosting provider support whitelist ip or they’re already whitelist cloudflare ip range.
I have no problem with VPS such as DigitalOcean or Vultr but i want to switch to shared hosting since my site have low traffic.

I am not aware of any such list of hosts. It’s best to ask the respective hosts whether there are any problems with Cloudflare setups to be expected.
