If you have webserver's logs for your domain for period since 12 Feb till now then yes you can rebuild the missing statistics. If you don't... then no. By default directadmin keeps logs for only last 5 days.
Manually... you might want to open a ticket with Directadmin support for official instructions. Or search the forums for them. Some time ago (2-3 years in the past... or even more) I wrote a script exactly for these purposes, i.e. rebuild missing data.
Currently I don't have a link for the mentioned post from these forums, and don't have instructions which will work with updated awstats scheme.
Probably somedoby else from the forums have another tested solution.
