Connect Linear Actuator Directly to Pixhawk

Hello,

I was not sure which category this topic belonged in, so I decided to post my question here in the Uncategorized section.

My team and I are using a 6 V electric linear actuator combined with the 32 Bit Radiolink Pixhawk Flight Controller to drive the steering mechanism of our vehicle. We are also supplying the Pixhawk with a 12 V power source. The main concerns of our project are cost and weight, so we are wondering if we can connect the linear actuator directly to the Pixhawk without the use of a motor driver or relay.

As a follow-up question, if we can connect the linear actuator directly to the Pixhawk, can we still code the Pixhawk to control how far the linear actuator extends and retracts? Or is a motor driver needed for that level of control? Below are links to both the linear actuator and Pixhawk we are using:

I would greatly appreciate any help or advice anyone could provide. Thank you.
