Dnssec and siteground

hello this is my current setup:
domain registrar: internetbs
hosting: siteground
cdn: cloudflare

I would like to use cloudflare dnssec; but when i go to the dns ta, i don’t get any settings and they point me to siteground interface. siteground don’t have any dnssec setting though. how can i access cludflare dnssec settings if my hosting is on cloudflare?

If you’ve set up your site’s Cloudflare plan through Siteground, you’re going to have to have Siteground check this out. I also suggest you contact Cloudflare Support, as they may know why you can’t set up DNSSEC through a hosting partner.

Login to Cloudflare and then contact Cloudflare Support by clicking on the Get More Help button.
