Is Serial Download available after setting BT_FUSE_SEL to 1?

For our target PCB, we need the GPIO that are used for Boot Configuration.

We would like to set the eFuses for BOOT_CFG1 and BOOT_CFG2 to set up QSPI NOR Flash.

To make the eFuses take effect, we have to set BT_FUSE_SEL=1.


But then, can we still access Serial Download?

The Reference Manual (table 21-9, page 1114) does not specify what happens if BT_FUSE_SEL==1 and boot_mode=01 (Serial Download).
