Applying EA/ED to Ivies without subject test scores?

Test just got cancelled, again. I have only one subject test score (780 in non-core subject). Do I apply EA/ED with just one subject test score (still deciding on schools, but my top choice still mentions subject tests as optional but recommended) or Do I must wait and apply To this school regular decision (Which basically kills all my chances) once I have the score, assuming it’s a good one?
How low a subject test score would you submit for HYP this year? Is It still 750+ Even for fall 2021? What about scores in 730-740 range this year? Or don’t Even bother for HYP with a 730?

All Ivy’s are test optional or test blind for Subject Tests this year. The absence will not be a negative.
