Bvp with unknown parameter

I am trying to solve a BVP with an unknown parameter using BVPc. Can I specify the range for an unknown parameter or can I set them to be strictly positive to help the solver pick up correct solutions? For example, let's say my unknown parameter is a radius. Then I know it can not be negative. Can I somehow pass this information to solver?

Try this using a good initial guess: https://de.mathworks.com/help/matlab/math/solve-bvp-with-unknown-parameter.html

Thank you sir, but as I am changing the initial guess, the solution goes on changing.
