Electronic – Reduce flickering on cheap 220v AC GU10 LED Lamps

As I am unable to find exact answer anywhere, I am looking for some help.
First of all, I'll explain the current situation.
I have a freshly built appartment where noone ever lived before. We decided to go for LED lights in all rooms and all lightning zones. The wiring is done for every room and every room has its own fuse. In my country we have 220v 50 Hz.
Time has come and we started looking for GU10 220v LED bulbs. We bought a set of 9 bulbs (4 or 5 W each) for one room and another set of 15 bulbs (3w each) later for second room.
Also, we are using the touch switches from Livolo brand everywhere, so, no mechanical switches.
None of the currently installed bulbs are dimmable, but we plan to add dimmable ones for living room.

So far, so good, everything works, except the strange feeling to my eyes on movements.
I started some small research. I found out what is AC, what is DC, what is 50Hz, and after all, what is flickering and what is a cheap LED Lamp with bad LED driver inside. I also tried capturing some videos using manual shutter and the flickering was visible.
Considering all this, I have some questions, but please answer them as simple as possible.

1. Is there a technology (some box, converter, rectifier, capacitor, etc.) that can be installed already at the beginning of the circuit (after the fuse box) to drive all the lights in appartment with reduced flickering safely, while keeping in mind we're using touch switches? With technology I mean a ready made product which is safe, rated for the total wattage and is in one piece.
2. If yes, will it work with the touch switches and the future dimmable touch switches and dimmable leds? Livolo switches are phase-cutting / Leading Edge dimmers.
3. Will choosing a more expensive LED lamps solve the problem with flickering?
4. If nothing can be done, except buying better LED lamps, which brands are flicker free?

At the moment we have only bought 9 + 15 leds for 2 rooms, 6 high lumen white light led lamps for bathroom, 1 high lumen led + 2 low lumen spotlights for toilet, none of them dimmable.
Touch switches cost us a lot of money, so, they won't be replaced.
If you require any morespecific information to answer my question, please ask and I will give everything I can find.

I just can't describe my anger on all this LED situation… if I ever knew anything similar will happen, I would have just chosen another solution, before buying…

P.S. Sorry my primitive english, it's not my native language. And thanks in advance!
