The socket 206037-1 has a rear thread for what I believe is heat shrink strain relief detailed possibly here? https://www.te.com/usa-en/product-CAT-AM71-C83998.html

What strain relief part fits the above socket?

I do not see any backshell 17 with heat shrink. https://www.digikey.com/en/products/filter/backshells-and-cable-clamps/313?s=N4IgjCBcoExgrFUBjKAzAhgGwM4FMAaEAeygG1wAGADgE4B2SkAXSIAcAXKEAZQ4CcAlgDsA5iAC%2BRMLTpIQqSJlyES5EE2ZSQAWgAs8xcvxFSkCgGYwF6iwnaY65G2QACAEYZkAaxwALPCwsOyA

Is there a strain relief backshell for 17 without heat shrink?

I believe the results in the linked search are back shells for 17mm TE connectors and it looks like they all provide mechanical strain relief.
