way to make two elements invisible?

[1140310118]

Hey, thanks for your contributions for github community.
I wonder, in linear-attention, is there a way to make two elements of the sequence invisible?

In the original self-attention, this is easy, only by modifying the attention matrix to achieve.
But in linear-attention, I can't find a way to achieve this goal, because there is no attention matrix.
Therefore, I would like to ask if there is a way to achieve this by modifying q, k, v.
