Website cloudfare Timeout

Hello, My website runs on wordpress and I have a lot of products (17k) on it. There are a couple of things that I try do which results in the Cloudflare timeout message appearing. Is there a temporary way around it as the main task I need to do is just a once off thing but I cant do it when the Cloudflare timeout message keeps coming up. Any help? Thanks
