Yes you can do it many ways.
Example. Create a filter rule that drops the connection, set it to disabled and add a comment (importante) to something. Here I do use "Test"
Then make a script that will enable this rule.
{
/ip firewall filter
set disabled=no [find where comment="Test"]
}
All in one line
/ip firewall filter set disabled=no [/ip firewall filter find where comment="Test"]
Then make a schedule to run in 10 days from now and add 0 sec for interval to run it only once.
