“Website” field in comment seccion https requirement

In every blog post, I allow visitors to write comments.
To write comments, a requirement is to type in “Name” and “Email”, and then I give them the option to type in their “Website”, so there are 4 fields in the comment section. Name, email, website, and the actual comment.

The problem is, that when people introduce their website url, in the “Website” field, it does not allow them to skip the “https://” or “https://” at the beginning.

Before posting this question, I tried in 2 different blogs and it was allowed, so it has to be some kind of configuration.

Then, a friend showed me that the demo for hestia had the same requirement.
How can I remove that requirement ??

Thank you in advance.
