TLS EOL work around?

We are currently working to get our version of SAGE 100c Advanced 2017 (Version 5.40.2.0) upgraded to the latest and greatest with our SAGE consultant company.  We have been working on it for Months but due to customization of the product it is taking time.  We are fast approaching the deadline of the 45 days after October 15th, when we are told our current version will become read only.  MY hope is that is that our consulting company will come through and finish the upgrade before November 15th but if they don't does Sage have any kind of temporary work around to keep people like us running until we can get upgraded?  From what I have been told our consulting company is working on 80+ upgrades that are directly effected by this issue.
