I had to ditch the usual Adafruit_NeoPixel library for my project so I tweaked pins.h, adding for ADAFRUIT_QTPY_M0:

&sercom3, SERCOM3, SERCOM3_DMAC_ID_TX, 11, SPI_PAD_2_SCK_3, PIO_SERCOM_ALT,

to the sercomTable[] values. Now I can DMA drive the NeoPixel without interfering with my code (see context).
