I can't recall any memory of seeing natives in modern or historical media as having any facial hair. Is this accurate? It seems odd, if my memory serves me correctly, that they wouldn't have beards and such, being the nomadic and rugged people that they were and still are in certain places. I'm sure in some artistic renditions of native Americans, they have facial hair but I'm drawing a blank on any that I've seen in which they do.
Some Native American men CAN, in fact, grow facial hair (I have a Native friend with a goatee, for instance) but many American Indians cannot grow full beards. It's a weird quirk of evolutionary genetics. Native and Asian men tend to have less body hair overall.
Culturally speaking, too, beards didn't carry the symbolic weight for American Indians they did for European Americans. There is a reason, for instance, the United States elected so many bearded officials in the mid to late nineteenth century. For whites, beards and mustaches came to assume a symbolic weight associated with masculinity and respectability. This is also a generalization, Ely S. Parker - the Seneca lawyer, engineer, and diplomat had a goatee and mustache, but this was largely in an effort to look like his European contemporaries. Assimilation in some respects.
Trends and ideas change, however, so now you rarely have politicians with beards or mustaches. The last facial haired president was William Howard Taft, who had a mustache.
