Hi, I'm going to use a microprocessor supplied with 3V3.
NHD-0212WH-ATMI-JT display must be supply at 5V0.

Considering parallel communication (bidirectional), Is there a way to obtain a communication between uC and display without using bidirectional level translator?

Without using a Voltage translator its hard to say what whether the controller will recognize the 3.3v bits as a '1'.
There would also be issues with the contrast when powered with a 3.3v input.

We would be able to offer this display as a 3.3V display, however this will require a MOQ.
If you are interested in this option please email
