Can you change your tax regime while filing your ITR? - Is it possible to change your income tax regime while filing your income tax return (ITR)?

If taxpayers filing ITR-3 or 4 choose to file taxes under the old tax regime, they will get only one opportunity in their lifetime to re-enter the new tax regime. However, after these taxpayers switch to the new tax regime, they cannot again switch to the old tax regime. Are there multiple switches between tax regimes allowed for those filing ITR-3 and 4?
