Dynamics 365 FTPS settings

Hi,

I have a quick question.  We have a running FTPS server, we want to use this withint ax365, but there is only the option SFTP settings?  Is the microsoft built-in ftps server not supported anymore in AX365??  Can someone provide us with a solution so we can use our ftps server to get this environment ready.

and in worst case , if my FTPS server isn't supported anymore, anyone got a trustworthy free FTPS alternative running on windows server 2016?

Thanks in advance.

greetings
