The movies have too much influence....
Of course elves can have facial hair. Dwarves do, hobbits do, humans do...hey, maybe even some
orcs do!
As for Eöl, his initial description says
Quote:
|
...a tall Elf of a high kin of the Teleri, noble though grim of face; and his eyes could see deep into shadows and dark places.

Nothing to prove or disprove him having a beard.
