Disable uart TX pin but use RX

[handmade0octopus]

Hello!
Slowly moving from 2.X.X arduino (finally).

Question about uart though. Before I used .end(true) to completely detach pins as I only want to use RX part of the Serial as one of my pins is used for dual purpose at boot.

Seems like with new changes I am not able to do that and begin when passed -1 will always default to some pin.

Is there workaround for this or maybe we can get back .end(true) that will also set the pins to value to not use it at all?

Here is simple code of what I am talking about:

Serial1.begin(115200, SERIAL_8N1, ENC_B, I2C_SCL);
Serial1.end(); // before - .end(true);
Serial1.begin(115200, SERIAL_8N1, ENC_B, -1);

Thanks for all the help!
