Quick look seems the Adafruit lib doesn't include pin changes.
In the Teensy SPI library is this:
// Teensy 3.x can use alternate pins for these 3 SPI signals.
void setMOSI(uint8_t pin);
Do a forum search...
Yes, that is right for pins 11 and 13.
If there is a way to specify the alternate pin 14 for SCK in the software, then that can be used.
If you chnage one alternate pin that is independant of other optional ALT pins,...

TD 1.57b1 available - if IDE 2.0 tested/used check the build dir the IDE uses. After 1.57b1 installed IDE 1.8.19 still used %appdata%\...\1.56.1 install, not where installed in the IDE unZip folder.

Good luck. Flash use works well - can support multiple files and functions great for static storage.

Yes, a suitable converter is needed - watch the voltage before making any connection.
From Wiki Voltage levels:
Those voltages are not Teensy UART pin compatible.
Neutral on naming here - as long as there are examples exposing the needed interface.
