There is a batch which is scheduled to run everyday at 5pm.

We are currently running the batch on adhoc at 12pm and its 4pm. We want to unschedule the run for 5PM and continue the currently running instance so that it does not coincide with its scheduled run.

Please help.

Where the batch is scheduled and which scheduling tool you are using?

A little late but assuming the Director - just unschedule it. All you are doing is removing an entry from cron (or at) which will not affect anything currently running. If this is a "run every" schedule, you'll need to add it back when it's time to get back on schedule.
