[Dune] Non Linear Solver in DUNE

I am relatively new to the functionalities of DUNE.
I want to solve a non-linear multidimensional problem. How I do it is, I
approximate it as a quadratic & compute the hessian. Then, I do Newton
iterations to solve it.
So, I approximate my non-linear problem as:
L (x + del (x) ) = 0.5*del(x)(transpose)* A * del(x) + b * del(x) + c
where A is the hessian.
Then I solve, A * del (x) = - b
& update x = x + del (x) for the next Newton Iteration.
*I want to know if there is a non-linear solver in DUNE, which can do
everything for me, if I input the hessian matrix?*
Thanks in advance.
