Waveshare do a number of Pico-like boards:
RP2040-Plus
[RP2040-LCD-0.96]( h ttp://www.waveshare.com/rp2040-lcd-0.96.htm)
And the equivalent using ESP32:
ESP32-S2
[ESP32-S3]( h ttps://www.waveshare.com/esp32-s3-pico.htm)
I take it that the Sixfab Pico LTE would be compatible with the 2040-based boards, what about the ESP32-based boards please? And has anyone tried?
