I Have UAE valid D/L is there any possibility to change my UAE D/L to Qatar D/L Now I'm in Qatar with Tourist Visa
On tourist visa, i believe you can drive for one month with a valid driving license of your country. In your case, UAE. However, to get Qatari license, you need to have Qatar RP.
Absolutely no way. Also, to get a Qatar driving license, you must be holder of valid Qatar ID.
