How to modify kernel dts of a10_soc_devkit ?

Hi,

We are using altera arria 10 soc(10AS066KF40) and building the OS image by taking reference of this link https://rocketboards.org/foswiki/Documentation/A10GSRDV1501BootLinuxFromSDCard

some of our hps signals are mapped similar to this schematic https://www.intel.com/content/dam/altera-www/global/en_US/support/boards-kits/arria10/soc/Production_files/a10_soc_devkit_03_31_2016.pdf

we are thinking to use the image as per above link but some hps signals are different so is it possible to modify dts/kernel/hps signal according to our custom hardware?

Thanks.
