Maybe not how you’re supposed to but put something like a business card between both blocks and the rotor

Why doesn’t it work? What is happening that makes you say it doesn’t work? That would really help diagnose the issue.
Your washers on the calliper bolts look like they’re the wrong way round. What are they there for? They should be seated so the dome shaped on fits in the dome shaped gap on the other one. Personally I’ve never used these type of washers on disc brake callipers before – maybe try just removing them? Are your bolts too long and you’re trying to space them out? Cut the bolts down ideally if that’s the case.
In the photo the calliper isn’t actually tightened up. Is that as tight as you can get it?

This method is only successfull if you alternate between bolts while tightening in small quarterturns while keeping the lever shut.
If you tighten one bolt and then the other, it will almost certainly go wrong.

Looks like the cone washer is upside down. 🙃 The convex and concave surface should mate allowing the caliper to tilt slightly during alignment.

the washer stack on the caliper mounting bolts is wrong is too many ways to explain. find the diagram for mounting your caliper and put the washer stack together correctly.

Your 20mm plus caliper adapter is on upside down. Thicker part goes up with the longer bolt.

the adapter is mounted upside down – the thicker part needs to be at the top.
Yes, the spacers are also setup incorrectly. But adapter orientation is the more pressing issue
The spacers should NOT be between the caliper and the mount adapter. That’s true on some brakes, but a Shimano caliper like this should be mounted directly to the adapter.
Those rounded interlocking spacers are, however, mid-ranges. The convex spacer needs to fit into the concave spacer. The diagram above makes that clear.
I am not certain if the mount adapter is oriented the correct way.

It looks like the rounded washers are in there wrong.
