For SSH we have two security modes, the first “Normal” is for greater compatibility (and less security) and the second is “High”. The high level provides a more locked down environment by using more secure KexAlgorithms.

You can access this from the main menu by enter /n and then 22.

In the submenu select option 3 for security access to choose between Normal and High.
