Hello Aspirant,
If your 12th-grade transcripts are digitally issued by the official board (with a digital signature or QR code present), it is generally accepted. If the transcripts are a scanned or downloaded version without the validity features, the authorities can request to see if you can provide a physical or attested copy at a later stage. It is always best to keep the original should a verification be required at some point.
