Is any way to get f2fs on cache partition?

Hi, 6p users.
I am using my fast nexus 6p.
But I want to use more fast performance.
So I try to format cache partition but failed :crying:
So I search about this problem and I found cm13 jgcaap's build support formatting f2fs on cache partition.
But I want to use ota support rom.
Is there any rom support formatting f2fs on cache partition with ota?
Thanks. (and sorry about my bad English.)
