Can I apply for a Thai DTV visa one week before the three-month requirement?

The user is inquiring about the possibility of applying for a Thai visa one week before the expiration of the three-month period necessary to show 500,000 THB in their bank account. They express a preference to be in Thailand by the end of November instead of December and are seeking advice on whether such an early application could result in a visa rejection or if they should wait until the entire three months are completed.
