Check User Manual, Solder bridges SB16 and SB18 link PA_6 and PA_5 to PB_6 and PB_7 respectively. The Solder Bridges are there to give i2c compatibility with Arduino Nano form factor. SB16 and SB18 need to be removed to 'float' PA_5 and PA_6 and hence the DAC outputs. reference User Manual UM1956 Page 19/20 Table 7 SB16 and SB18
