I dont believe this prevent it. But, SDWAN with hardware you need to be willing to spend a little bit because physical devices with SDWAN IOS will not be found in old device. We are talking about something with IOS-XE at least.
You can try to find Vipitela hardware maybe. But I believe most of SDWAN LAB is virtual for this reason, not easy to find affordable device with SDWAN support.
