Is there any instances where double for less is an acceptable play??

As fate has it, recently there are some life changing events that caused me to decide to invest more and put up a larger risk appetite on BJ.

I have increased my bet size and session Ror to almost fully kelly. As a result, when I push out a max bet, or what somebody calls a super max bet. I'm hesitant to double per strategy to protect my BR.

Is there instances where doubling for less is acceptable? I wouldn't hesitate on a 10 vs 6 of course.
What about A2 v 5? 8v6?
Or is it better to just hit?
