This is the second time in Trek history to decide how these things work. TOS, TNG and DS9 were straightforward three-letter acronyms. Of the others, ENT would suggest DIS is the correct form, while VGR would rather support DSC (but many use VOY anyway, this having been the first time of any real ambiguity).
STD would be the one without any support from precedent, as the letters for the words Star Trek are not included in any of the other TLAs, except perhaps by preceding them, separated by colon.
