This JAMF Nation article may point you in the right direction to develop your script, then you can just call it via a Policy at the determined interval.

@andrew.nicholas Thank you for the suggestion. This is the script I have so far? Do you have any insight?

# ABOUT THIS PROGRAM

NAME

enableFileSharing.sh -- Enables or Disables Personal File Sharing on Mac OS X Clients.

SYNOPSIS

sudo enableFileSharing.sh

sudo enableFileSharing.sh <mountPoint> <computerName> <currentUsername> <enableFileSharing>

If there is a hardcoded value specified for <enableFileSharing> in the script,

or if the parameter is not passed by The Casper Suite, the hardcoded value in the script will

be used.

The data that is specified for the <enableFileSharing> parameter should be specified in one of

the following formats:

"t" "T" "true" "True" "TRUE"

"f" "F" "false" "False" "FALSE"

"y" "Y" "yes" "Yes "YES"

"n" "N" "no" "No" "NO"

DESCRIPTION

This script enables or disables the Personal File Sharing preference on Mac OS X 10.3 or later.

It can be used with a hardcoded value in the script, or read in as a parameter.

Since the Casper Suite defines the first three parameters as (1) Mount Point, (2) Computer

Name and (3) username, we are using the fourth parameter ($4) as the passable parameter to

acquire the status of <enableFileSharing>. In addition, the fourth parameter is utilized to set

the enableFileSharing parameter.

If thats the script straight from the Scripts page of JAMF Nation I imagine it would be fine but I would test first to ensure it works as expected.

This part of the script will fail if run on Yosemite and up

OS=/usr/bin/defaults read /System/Library/CoreServices/SystemVersion ProductVersion | awk '{print substr($1,1,4)}'

Its been well posted about on other threads that many of JAMF's older scripts using this method of checking the OS version fall down when run on 10.10.
