How to remove/hide body parameter from Swagger UI in file upload API

Hello, I'm newbie to swagger UI development using jersey framework. I'm looking out for the resolution for below mentioned issue.

Issue: Unable to remove/hide body parameter from Swagger UI

Please find my Java source code:

@POST
@Path("/createSchedule")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces({ MediaType.APPLICATION_JSON })
@ApiOperation(httpMethod = HttpMethod.POST, value = "Create a new export schedule(s)")
@ApiImplicitParams({
@ApiImplicitParam(name = "file", value = "Upload the template (.xlsx) to create schedule(s).", required = true, dataType = "file", paramType = "formData") })
public Response createSchedule(@FormDataParam(value="file") InputStream inputStream,
@FormDataParam(value="file") FormDataContentDisposition fileMetaData) throws ScheduleException {
}

I have used Jersey 2.29.1(jersey-container-servlet) & Swagger 1.5.0 (swagger-jaxrs) API's. Also do let me know how to allow only specific file extensions (like .xlsx) to upload from swagger ui.

Thanks in advance! Cheers!
