Can I get on and off at Gu 'an from Beijing to Xiongxian?

You can get off. Generally, you can get off at the junction of the North Ring Road and Jingkai Highway, which is not far from Gu 'an Station (Gu 'an stands next to Jingkai Highway, and usually goes south after getting off 100 meters, just on the east side of the road). Of course, if you go to other places in Gu 'an, you will stop as long as you pass by. If you get on the bus, the driver will not go to the station. You can ask the driver in advance where it is convenient to get on the bus. I hope it works for you. By the way, I'm from Gu 'an. Hehe, I have been in the car you mentioned.
