Converting android tablet to a dedicated kindle

Hi,

I am not sure whether this is a right forum to ask. but I have this question

I have a old LG Android Tablet and I want to convert it to a dedicated book reader like Kindle. I searched the web and everywhere I am getting link to convert Kindle device to a android tablet but not the vice versa.

Is it really a possible? I know about the kindle app but I want to get rid of android OS and have a dedicated kindle reader.

is that possible?
