“Accidentally deleted partition, possible to recovery?”

Last night, when I was trying to install windows 10 onto a new SSD, I accidentally deleted one partition on my storage drive. The storage drive was just a NTFS formatted 3TB drive that was not broken into smaller partition. I don’t want to lose this partition since there are important data within it. Is it possible to recover this partition deleted accidentally in Windows computer? Any suggestion is appreciated!
