I have had occasion to look real close at 𒀭𒄑𒉋𒂵𒎌, and I get why 𒀭[DIĜIR] is there, and 𒉋𒂵𒎌 [BIL₂.GA.MEŠ] are clearly phonetic components---but what the hell is 𒄑 [GIŠ] doing there? it's not pronounced (evidently), but as a determiner it doesn't seem to make much sense to me (used for wooden objects and trees), and 𒄑𒉋𒂵 [(GIŠ) BIL₂.GA] as "male ancestor" with a determiner for wooden objects/trees *haunts* me, but I can't find a source for that. What's going on with 𒄑 in this name?
You know, I can't find a good source on why 𒄑 appears in this name, as I don't think scholars agree on why it's there. The most common theory seems to be that the bilga element may derive from pabilga 𒉺𒉋𒂵 "paternal grandfather, paternal uncle". Halloran lists bilga as being "a plant-breeder's terminology for a human ancestor", as pa 𒉺 has "branch" as its most basic meaning, like the branch of a family tree. Somewhere along the line, the 𒉺 sign of (pa)bilga got reinterpreted as the similar-looking 𒄑 (and related meaning, branch > tree), and thus got stuck in the name of Bilgamesh and presumably others derived from the same root.
However, not all sources agree on pabilga as being a proven etymology for bilga at all, so take all this with a grain of salt. And check out this prior post on the meaning of Gilgamesh's name.
