I have a device which excist of three modules.

I think you mean, "consists of 3 modules".

These modules have to be connected with a bus.

Is it a specific requirement that it has to be a bus?
Could you use a "daisy-chain" instead?

Length of the bus is 1 meter

Is that 1m within an enclosure, or between separate pieces of equipment in different enclosures?
What is the environment - is it "noisy"?

at most and has low traffic.

Please be more specific - what is "low"?

I don’t want to use a UART

Why not?
I'd have thought that a UART in 9-bit mode could be ideal here...

or CAN or something simular

Again, you need to be more specific - what else, precisely, are you discounting as "similar"?

So I was thinking about buffered I2c.

Yes, that's a possibility.
