No, not unless your visa is for a duration longer than three months.
To convert your current driving license or an International Driving Permit into a Vietnamese driving license, the applicant must first hold a valid Vietnam permit of at least three month's validity and a current driving license or a valid International Driving Permit.
Another source states this clearly
g) Foreigners residing, working and studying in Vietnam for at least 03 months, having Diplomatic or Official Identity Card, Permanent Residence Card, Temporary Residence Card, stay permits and unexpired native driving licenses may apply for renewal with corresponding driving licenses of Vietnam if they wish to drive in Vietnam;
enter Vietnam from 3 months and above
I believe that is a mistake in translation. For makes much more sense there
