Is it possible to enable IP blocking in order to prevent respondents to replying more than once to the same survey/form?

You can set this option in the form preferences under the form limits, select the strict check option to block based on the IP address, see screenshot below
You can also use the unique question to use a field like email to allow only unique email addresses in your submissions
