PR is a US territory and as such subject to US immigration laws. Whatever the perception the college personnel has in PR (I have my own pet peeve regarding University personal giving out immigration law advice on daily basis) to change status to that of a foreign student you need to be in a valid non immigrant status at the time of the application.

A requirement for an F-1 student visa is an unrelinquished foreign (outside US) residence to which you intend to return. This is incompatible with DACA, which requires residing in the U.S. I see no way you can qualify for an F-1 visa unless you leave the U.S. and set up residence in your home country, but then you would give up your DACA and would be subject to the 3 year bar for unlawful presence over 6 months.
