Odoo 13 Enterprise

In ~/enterprise/account_reports/models/account_report.py when you select elements for a report, such as the Accounting -> Audit Reports -> Trial Balance report, it sets a session variable; in this instance, one named "report:account.coa.report:false:7"  (See screenshot)

I'd like to be able to delete, or better yet, edit this variable when I change companies:

How can I do this?  What can I inherit/intercept/override so that when the company changes, I can read and then edit (or just delete if I have to) that session variable?
