Required condition in the fields - filter to enable save draft

Hello,

Thank you very much for the required condition option.

I have many custom fields with the required condition, in this scenario without meeting the condition, my posts are not saving in the database (auto-draft).

So, is there any hook to save the post as a draft even the required conditions are not validated? I need the required validation only to block the 'publish' option.

Note:
- enabled save field option in the meta box
- disabled the posts_revision in the wp-config

Thanks.
