When can I JUST use TM internet modem as ONLY a modem, in BRIDGE mode, with NO NAT, NO firewall, and frankly NO Wifi.

PLEASE let me know when can get a PLAIN modem from T-Mobile, or BUY my own modem, or SET their modem up to DUPLICATE the functionality of Spectrum.

Easy answer.  Never.  In fact each new "modem" they release has less and less options and that's the way they like it.  Unfortunate, but true.  If I had *any* other alternative, I have two choices…  DSL at 1 mbps, or Satellite at horrendous latency, huge prices, and loss of signal all the time.
