Tl;dr can you still buy the individual levels of battle pass for 250 gold and if so, how?

I remember this being a thing in the past, but I can’t find any mention of it now. I’m probably gonna be a few levels short of reaching the next token in my 2nd path when this season ends in 4 days. Have already set aside some gold to buy the extra rewards for the first path (completed all 5p lvls on that one).
