Do you suggest to enable "Crawler Hints" at Cloudflare?

I was reading Bing docs in order to find out why they deindexed my site...

As far as I tell there is no reason, they deindexed my site several months ago.
I contacted support in January and they replied in May informing "did not meet the standards set by Bing the last time it was crawled."

So today I was trying to find out the reason but I see no reason, not even a hint...

Then I came to know about Bing's "IndexNow" thing and it took me to enabling Cloudflare's "Crawler Hints"
So wondering if it's something important and should I enable it or not... What you guys suggest?

Thanks for your time and kind suggestions...
