boot partition expansion

Hi folks Well all is well after the previous mess apart from one thing that i must admit i forgot to tackle on the reinstall a few days ago my "/boot" partition is too small 300mb ran into a problem last night pacman installing kernel 6.7.0 The main kernel built installed fine but the fall back errored out with no room on . I have a spare empty partition sda2 of 40Gb sat doing nothing can i grow the boot partition to take some of that spare space without risking another reinstall Sorry to be a pain right now but i got enough medical issues right now and this is just bugging me beyond sanity Any help would be greatfully received Thanks Pete .
