Is it possible to restricting traversal through certain edge while using bfsearch function in matlab

I am using bfsearch on my graph with the following source and target nodes

s = [1 1 2 2 4 ] t = [2 4 3 8 3]

I want to start the traversal from node 4 but also restrict the traversal between node 4-3.

So the traversal should start from 4 -- 1 --- 2 --- and so on.

is there is any way of editing the funtion bfs in matlab or maybe a command to restric the traversal thorugh certain edge ?
