Guys, I have M3LR, Castrol SRF 1000ml, 4x Steel Braided Brake Lines and I want to know do I need more brake fluid or 1l is enough?
1L should easily be more than enough.
It's 1L if you have 2 liter bottles on hand.
2L if you only have 1 bottle on hand.
Murphy's Law.
I can't find the information about HOW MUCH brake fluid do I need to completely bleed/flush the whole system and replace with the new fluid.
How "fully" do you intend to bleed/flush the system?
Activating ABS pump to flush it? Just pressure bleeding the lines?
The latter is likely to be under 1L. The former - who knows, none of us do that at home!
Unfortunately, Castrol SRF is selling only in 1l bottles.
True, but you can buy 2 bottles, and save one for the next brake fluid flush (annually if you track the car, every 2-3 years otherwise). Disregard the silly advise Tesla gives about "testing" fluid, if you want to have brakes when you need them.
Watch for the color change from the old to new fluid.
Unless your old fluid is heavily contaminated (unlikely, but not impossible), or you are switching between brake fluids with different color pigments (harder and harder to find), watching for when new fluids arrives by color shift or presence of bubbles may be a challenge.
Rear brake lines are longer, and will take more fluid to flush. You may have to estimate how much fluid it takes, or watch your fill reservoir consumption rate (if using transparent pressure bleeder). Like this one:

BTW, I found that Tesla's brake fluid cap is identical to that of GM.
HTH,
