You have to copy

; remove PSRAM support -> avoid "blinking" of GPIO 16/17 at boot
[env:tasmota32-nopsram]
extends                     = env:tasmota32
build_unflags               = ${env:tasmota32_base.build_unflags}
                              -DBOARD_HAS_PSRAM
build_flags                 = ${env:tasmota32_base.build_flags}
                              -DFIRMWARE_TASMOTA32
                              -DDISABLE_PSRAMCHECK
                              -DCODE_IMAGE_STR='"tasmota32-nopsram"'
                              -DOTA_URL='""'

in your platformio_tasmota_cenv.ini

After you have done restart VSC!
