golang read directly from blocks

I have a file of roughly 300MB. and I run the following command on Linux:

sudo debugfs -R "stat /home/user1/Documents/test.csv" /dev/sda2

I get the following output:

I think the EXTENTS: shows the physical blocks of the file.

My question is, is it possible to directly read from these block numbers in golang as byte array?
