I found by myself !

You need to set the option byte OPT2 = 0x02 (NOPT2 = 0xFD) to enable TIM2 CC3 and disable TIM3 CC1, following is the asm file to add in your project :

;This file contains the values to program in the option bytes.

;You can change the values below according to the device datasheet.

;Be careful to respect the complement bytes,

; or the default values of the option bytes will be used.

;See the device datasheet for more information on the meaning of each bit.

cseg at 04800h

db 000h ;LOCKBYTE

db 000h ;OPT1

db 0FFh ;NOPT1

db 002h ;OPT2   //0x02 will enable TIM2 CC3 and disable TIM3 CC1

db 0FDh ;NOPT2

db 000h ;OPT3

db 0FFh ;NOPT3

db 000h ;OPT4

db 0FFh ;NOPT4

db 000h ;OPT5

db 0FFh ;NOPT5

db 000h ;OPT6

db 0FFh ;NOPT6

db 000h ;OPT7

db 0FFh ;NOPT7

end

An easy way can be to set OPT2 which is AFR option through STVP.
