Complicated products discount scenario

I need to make this scenario in my catalog with magento 2.4.3.
I use a catalog price rule which gives a 10% discount to some products of a certain brand. I have this rule created easily with conditions.

But the same products I need to get 15% discount in cart if customer buy 2 or more products from same brand. I also created the cart price rule with conditions.

Here comes the problem.

Magento in cart when you add 2 or more product(where the cart price rule applied) creates additional 15% discount to the products. This is not needed.

So now the product has a 10% discount when you buy it alone( which is right) but if you add another piece you get 10% + 15% discount which is wrong for us.

We need the 10% discount for the 1 piece but 15% discount in the initial price when 2 or more pieces added.

Is there a way to achieve this?
I can’t figure it out.

Thanks in advance
