How to get Android Phone storage as a drive path in Windows PC

I am using MI Note 5 Pro android version 9.0 and Windows 10 Basic.
On USB plugging('File Transfer' selected), I can only access files from Phone by normal copy paste(ctrl-c/v) but cannot access full file path from Phone because there is no drive letter assigned.

where disk is sd card.

I am getting files path as "This PC\Redmi Note 5 Pro\Internal shared storage" but want something like "P:\Redmi Note 5 Pro\Internal shared storage" How to get it without rooting phone?

Purpose: I want to backup my phone data to PC periodically using "Areca backup" open source utility which creates incremental backup. Note: I will not be writing any data to Phone but will only need to read it for copy operation.
