If you have a different phone number, you can try. I did the same and got wealth card. Only thing I lied was salary. I put 5 lac salary when asked. Everything from there was smooth.
Nothing guarantees it with IDFC. Only way is to write to them for limit increase and once Select has 5L or more limit ask for upgrade. There is nothing set in stone.
The method @Jetstone mentioned works. Here is my experience
Jan 2022 - got Select approved
2022-2023 - tried enhancement and upgrade multiple times. No success. Also tried to apply multiple times using using another phone number.
Jan 2023 - Out of frustration closed the Select card.
