Add an external pull-down resistor.

Thank u for reply.which Pin i put resistor boot pin or PB14

[waclawek.jan]

STM32G07x/0Bx?

Pulldown resistor won't help, bootloader holds PB14 (and PA6) hard high, see AN2606, footnote to the table for given model.

There's no workaround - if you can't avoid boot mode, you have to design your system with this problem in mind.
