Trouble Getting started with Stratix 10 SOC

Hi,
Really sorry for the long delay in getting back, was out of office.

First of all , this is the latest stratix10 user guide that we have, just in case if you didnt have it yet. 

https://altera-fpga.github.io/rel-25.3/embedded-designs/stratix-10/sx/soc/gsrd/ug-gsrd-s10sx-soc/#overview

Unfortunately, you cannot disable the security or secure device manager (SDM) as all configurations are routed through it, even if advance security features are disabled, SDM still enforces strict boot configuration.

For changing sysid in qsys , did you also update the device tree and regenerate the files out, also whether you're using Programming File Generator to generate the .rbf out?

Maybe you can take a look into the github examples on top to see the steps to build for stratix 10 ?

Thanks

Regards

Kian
