Can you train a dog not to be afraid of the world?

My 1 year old (next week) dachshund is naturally very timid and shy. We got her at 8 weeks from a good breeder, she’s never had any trauma or bad experiences. She also falls under the category some dachshunds share of “hates walks” and will only walk towards the house, not away from it. After months of consistency and carrying her to the destination and having her walk back, she started walking the last 200 ish feet away from the house. I felt like I could have cried I was so proud. Then after about 3 weeks of that going so well, she stopped and completely reverted to refusing to walk away from the house at all. I know it’s a fear response, maybe she’s thinking “what if we don’t go home? I’d rather be home”. I know she understands the concept of a walk and how to walk, she just doesn’t want to. Since it’s been about 2 or so weeks of her reverting in progress, I’ve just started going to the front yard or a non crowded park and just sitting with her for about 5-10 mins, feeding her treats and petting her. She will shake and quiver intermittently but has been accepting treats – sometimes when she’s nervous or doesn’t wanna be somewhere she won’t even do that so been considering that a small win. I don’t know what to do to get her more comfortable. This new idea I’ve got of the sitting and treating is new so I know I need to give that time, I just want her to be able to relax out and about more. I’m not looking for her to be coming with me to breweries or markets or anything like that, I just want our outings not to stress her out. She’s great in the car and great inside the house, just even in the yard if she hears a bang somewhere or someone talking nearby she runs to try to go inside. Anyone have any similar experience or guidance? I’m not sure anxiety meds would be an answer since she isn’t anxious all the time, just outside of the house or car. Am I doing the right thing trying to teach her to be neutral? Am I on the right track even though she currently shakes or should I somehow scale it back to where she doesn’t shake (if possible)? Thanks in advance
