Different banks and services can turn off the 3ds, the point is not that they are afraid - and you they are not credible.
3ds shut off on request by method of negotiations with the managers, but usually only after you have some time to work and show the lack of chargeback, and after consultation with the security service
For example, in practice Tinkoff Bank without 3ds used
it's best to lead talks with the banks and with integrators such as payture or cloudpayments
But even disabling the 3ds won't always help - some countries/banks on the contrary without 3ds not miss that the most appropriate technology is the dynamic 3ds which determines when is the best time to ask/not ask 3ds
in addition to the 3ds - the banks issuers of cards can also decline the payment due to the fact that the acquiring Bank will be from another distant country (Russia). The solution to this is to connect either a local acquiring from countries with whom you will work, or normal services like stripe - but then, you need a company in Russia
If your market is not the Russia you need acquiring services in the countries where you work, for sure you can start using the Russian acquiring/paypal to accept cards, but then for normal operation will have to open a company in USA/Europe
