Possibility of reducing the notice period upon resignation

I am planning to resign from my current company in the UAE where I have worked for 6 years.

My employment contract currently states that a notice period of 3 months is required.

I would like to request that this be reduced to 1 month. Note that I got a job offer outside the UAE.

Please advise how to approach the negotiation for the notice period, If they are not accepting the notice period negotiation.

How to take it forward? How to avoid the UAE labour ban if needed to work in the UAE in future?
