Can I pull-down boot0 with 10kOhm instead of having 3 pin jumper

STM32f103
In the design guide it recommends to have something switching between vcc and gnd with 10kOhm series resistor, and i need my design to be grounded by default so i may not solder the header even, is it okay if i left the design like fig 1 instead of fig 2, and would it cause issues if i needed to pull it high?

No issue. You may pull it down with anything up to 100k and provide some contacts for connecting it to Vdd for bootloader activation.

You may short BOOT0 to ground directly with a PCB trace if you don't need to invoke the bootloader via hardware.

The pull-up resistor has the advantage of allowing you to set the pin in question to a different level directly at the pin without creating a short-cut. If you are absolutely certain that you never want to switch the pin, you can also connect it directly to a fixed potential (e.g. GND for the BOOT pins) without a pull-up resistor. You can also omit the pull-up resistor if you use a switch/jumper.
