No, the main problem ist that it's locked by hardware:

From last_kmsg:

As u can see 683 MHz Step doesn't get voltage assigned at all. That's why anything > 572 MHz isn't available in the List from the GPU max freq from the a2n app.

But fortunately Cluster0 and Cluster1 CPU gets Voltage assigned to all Steps: :D

Right now tried if i can increase CPU Voltage .. did that:

But it didn't increase at all .. so it's all hard-locked.

Edit:2:

And currently DDR / RAM Clock is 1,8 GHz and basically the Hardware could handle up to 2,1 GHz .. but it's locked as well:
