There are many different types of hobby servos, and we do not recommend any particular one. Check the specification of any servo you connect to your Duet, in particular the idle, running and stall current. Generally, so-called '9g' servos should be okay to connect directly ... but larger servos should have additional protection, or be powered independently of the Duet.
The two servos you list are 9g servos, but the the idle, running and stall current are not listed in their specification.
