Use CloudFlare DNS manager and NOT MiAB DNS

Hi, I had successfully installed MIAB but only later did I realize that all DNS records after that will be managed by MIAB. I would like to manage all the records (and therefore also when I create a website for my company) and protect them with cloudflare. the mail server (mail.mydomain.com) must be separate and must only function as a mail server, not a DNS record manager. Also, when I installed MIAB, the root domain (mydomain.com) always led to the MIAB homepage. How can I do this?
