SoftwareSerial - using transmit only and use the RX pin for something else

Hello! I want to use an attiny85 for a project but I need to use all of the available pins. I will have an lcd display with a uart backpack and it only needs one pin for communication. My understanding (although it could be wrong) is that since the attiny85 doesn't have UART, I have to use the softwareserial library to implement that type of functionality. I would like to use one pin for TX and I don't need a RX pin. I would like to use the RX pin for something else such as a button input. Is this easy to do?

In the original SWSerial you could set a pin to -1 resulting in the use of only one pin.
I think this trick will still work.

And I recall - [Library] SoftwareSerialTX - A transmit only version of SoftwareSerial - Libraries - Arduino Forum -
give it a try
