Hi @Chris Burke ,
Thank you for posting query in Microsoft Q&A Platform.
When you Synapse Workspace in managed virtual network, all traffic from it will go via that Vnet only. Hence, it's not possible to have a linked service without using private endpoint.
If you would like to share this feedback to product team to have such feature, then kindly feel free to post feedback at below link and up-vote same. Product team closely monitor feedbacks and consider them for future releases.
