How can I control how nonces are generated?

[averissimo]

Is there an option to control the initial seed / increments of the nonce? (when solo mining)

I've been trying to read the code and my best guess is that it is being done in a infinite while increasing by 1.

edit: or just change the code on how it increments/decrements?

Nonces are tried in parallel, not sequentially... There is no "increment".
