Yes, FTPS is supported by the external, though you have to use the tsNet 
commands directly, rather than the standard libUrl calls.

For explicit FTPS transfers, you can do something like this:

local tEmptyHeaderVar, tData, tResultHeaders, tSettings
put true into tSettings["use_ssl"]
put "some data to upload" into tData
put tsNetUploadSync("ftp://ftp.domain.com/path/to/file.dat", 
tEmptyHeaderVar, tData, tResultHeaders, tSettings) into tResult

If you want to use the less common implicit transfers, you can do this 
instead:

local tEmptyHeaderVar, tData, tResultHeaders, tSettings
put "some data to upload" into tData
put tsNetUploadSync("ftps://ftp.domain.com/path/to/file.dat", 
tEmptyHeaderVar, tData, tResultHeaders, tSettings) into tResult

Hope that helps,

Regards,

Charles
