Can I extend my 90-day Non-O visa before the 45-day mark in Thailand?

A user inquired about extending their 90-day Non-O visa for retirement purposes, specifically if they could apply for the extension in mid-August while being out of the country 45 days before the current visa expires. Responses indicated that the earliest one can apply for an extension is 45 days before expiration, but they can apply anytime until the visa expires. It was also advised to secure a re-entry permit before leaving Thailand to maintain the validity of the visa.
