Yes, you can.
It is common to drink holy water in many Catholic countries, and in all Eastern Churches (Orthodox and Catholic).
Please don’t drink the holy water from the font, just bring a jug of water to the parish - any priest or deacon will bless your own water for you to take home.
At the risk of starting a never-ending tangent, there are actually different blessing formulations for blessing water for the faithful to use in consumption as opposed to the blessing for water to be used for baptism (which is what the font would have in it). And two different formulations for the baptismal water depending upon whether it is Easter season or not, to boot.
